Henry M. Loope José Luis Antinao Casey Jones Matthew R. Johnson 2025 vector digital data https://doi.org/10.14434/ijes.v7i1.41098 South_Kankakee_QG_100k is an Esri File Geodatabase that contains one feature data set with four feature classes, and five geodatabase tables detailing the quaternary geology of the Indiana portion of Chicago and northern half of Kankakee 30- x 60-minute Quadrangles. This data set conforms to "GeMS (Geologic Map Schema) –a standard format for the digital publication of geologic maps." For more information on GeMS please refer to the supplemental information within this metadata. The South_Kankakee_QG_100k geodatabase was created to provide Quaternary geologic information of the map area, including the spatial distribution of map units and corresponding descriptions, locations of boreholes, geochronology data, and other geologic point and line features. These data contribute to the characterization of mineral and water resources related to Quaternary sediments in the Indiana portion of Chicago and northern half of Kankakee 30- x 60-minute Quadrangles. This geodatabase is, in large part, the result of a cooperative mapping agreement between the U.S. Geological Survey (USGS) and the Indiana Geological and Water Survey through the Great Lake Mapping Coalition, a program of the USGS. South_Kankakee_QG_100k_V2 is a composite geodataset that conforms to GeMS (Geologic Map Schema)--a standard format for the digital publication of geologic maps", available at http://ngmdb.usgs.gov/Info/standards/GeMS/. Metadata records associated with each element within the geodataset contain more detailed descriptions of their purposes, constituent entities, and attributes.). An OPEN shapefile version of the dataset is also available. It consists of shapefiles, DBF files, and delimited text files and retains all information in the native geodatabase, but some programming will likely be necessary to assemble these components into usable formats. These metadata were prepared with the aid of script GeMS_FGDCMetadata.py, version of 2/27/24. 2025 publication date Complete As needed -87.5283 -87.0000 41.2523 40.9988 ISO 19115 Topic Category geoscientificInformation None Atherton Formation Martinsville Formation Trafalgar Formation Wadsworth Formation Glaciofluvial deposits Glaciolacustrine deposits Paludal deposits Lagoonal deposits Eolian deposits Alluvial deposits Fan-delta deposits Nearshore deposits Leroy member (informal name) Merrillville Member (informal name) Fan deposits Wedron Group Leroy member (informal name) None Indiana Lake Milwaukee Lake County Newton County Porter County Jasper County None.

Bloomington IN 47405-1405 US 8128557636 IGWSInfo@iu.edu Microsoft Windows 11 Version 23H2 (Build 22631.2715); Esri ArcGIS Pro 3.4.0 Geologic contacts and associated information were determined during 1:100,000-scale mapping of surficial material based on field observations and geologic knowledge of the mappers. Effort was made to ensure the accuracy of the geologic contacts and associated data. Confidence that a feature exists and confidence that a feature is correctly identified are described in per-feature attributes ExistenceConfidence and IdentityConfidence. Geologic contacts and associated information were determined through compilation of project field observations and boreholes, complemented with archived Indiana Geological and Water Survey maps and borehole data, Indiana Department of Natural Resources water well logs, and United States Department of Agriculture Soil Survey Geographic (SSURGO) data. Topology tests were performed to ensure the integrity of the data. These tests checked for polygon overlaps and gaps and line pseudos, dangles, and intersections. Dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. Estimated accuracy of horizontal location is given on a per-feature basis by attribute LocationConfidenceMeters. Values are expected to be correct within a factor of 2. A LocationConfidenceMeters value of -9 or -9999 indicates that no value has been assigned.

Geologic contacts were generated directly in ESRI ArcGIS Pro 3.4 by creating polylines at contact boundaries. Contact boundaries were determined by examination of LiDAR-based topographic and hillshade maps, United States Department of Agriculture Soil Survey Geographic (SSURGO) data, new and archived Indiana Geological and Water Survey borehole data, and Indiana Department of Natural Resources water well logs. Polyline features were converted to polygons using the “Feature to Polygon” tool and attributed with point data containing Map Unit identification. These polygons were imported into MapUnitPolys where topology was checked and corrected. Once corrected, MapUnitPolys was converted to lines and imported into ContactsAndFaults. Attributes were populated for ContactsAndFaults and MapUnitPolys based on GeMS requirements. 2025 Vector String 266 Universal Transverse Mercator 16 0.9996 -87.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 meters North_American_Datum_1983 GRS 1980 6378137.0 298.257222101 DescriptionOfMapUnits Non-spatial table that captures content of the Description of Map Units (or equivalent List of Map Units and associated pamphlet text) included in a traditional paper geologic map.

May originate from erosion of rocks and sediment or may be derived from marine organisms (of carbonate or siliceous composition). GeMS Lacustrine sediment, mostly fine-grained Mostly well-sorted and well-bedded material, generally silt and clay sized, with lesser amounts of sand, deposited in perennial to intermittent lakes. GeMS Fine-grained, felsic-composition intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at shallow depth beneath Earths surface, thereby cooling quickly. Generally fine grained but may contain large mineral crystals (phenocrysts). Mostly found as tabular dikes or sills. Composed mostly of light-colored minerals. Includes rhyolitic, dacitic, trachytic, and latitic rock. GeMS Glacial till, mostly clayey Mostly unsorted and unstratified material, generally unconsolidated, deposited directly by and underneath or adjacent to glacier without subsequent reworking by meltwater. Consists of heterogeneous mixture of clay, silt, sand, gravel, and boulders, ranging widely in size and shape. Relatively clayey in texture. GeMS Coarse-grained, felsic-composition intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at some depth beneath Earths surface, thereby cooling slowly enough for mineral crystals to grow large enough to be visible to naked eye. Composed mostly of light-colored minerals (for example, feldspar, quartz). Includes granitic, syenitic, and monzonitic rock. GeMS Rock Various rock types, not differentiated. GeMS Felsic-composition air-fall tephra Fragments of volcanic rock and lava, of various sizes, carried into air by explosions and by hot gases in eruption columns or lava fountains; known as tephra. As tephra falls to ground, with increasing distance from volcano, average size of individual rock particles and thickness of resulting deposit decrease. Because of their high silica content and resulting high viscosity, felsic-composition magmas tend to erupt explosively, readily forming pumice and volcanic ash. Composed of light-colored rocks (for example, rhyolite, dacite, trachyte, latite). GeMS Mostly carbonate rock Mostly carbonate rock, interbedded with other sedimentary rock types. GeMS Residual material Unconsolidated material, developed in place by weathering of underlying rock or sediment. Usually forms relatively thin surface layer that conceals unweathered or partly altered source material. Material from which soils are formed. GeMS Regional metamorphic rock, of unspecified origin Rock derived from preexisting rocks and altered by essentially solid-state mineralogical, chemical, or structural changes, in response to marked regional changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Origin of preexisting rock is mixed (for example, igneous and sedimentary) or is not known. GeMS Glacial till, mostly sandy Mostly unsorted and unstratified material, generally unconsolidated, deposited directly by and underneath or adjacent to glacier without subsequent reworking by meltwater. Consists of heterogeneous mixture of clay, silt, sand, gravel, and boulders, ranging widely in size and shape. Relatively sandy in texture. GeMS Ice-contact and ice-marginal sediment, mostly coarse-grained Mostly sand- and gravel-sized particles or clasts, with lesser amounts of silt and clay, derived from rock or preexisting sediment that has been eroded and transported by glaciers. As glacier melted, material was deposited by running water essentially in contact with glacial ice or was transported and deposited by glacially fed streams. Includes sediment deposited into water bodies adjacent to glacier. GeMS Intermediate-composition pyroclastic flows Hot ash, pumice, and rock fragments erupted from volcano. Material moves downslope commonly in chaotic flows; once deposited, hot fragments may compact under their own weight and weld together. Parental magma commonly erupts from stratovolcanoes as thick lava flows but also can generate strong explosive eruptions to form pyroclastic flows. Includes rocks that are, in color and mineral composition, intermediate between felsic and mafic rocks (for example, andesite). GeMS Ice-contact and ice-marginal sediment Mostly sand-, silt-, and gravel-sized particles or clasts derived from rock or preexisting sediment that has been eroded and transported by glaciers. As glacier melted, material was deposited by running water essentially in contact with glacial ice or was transported and deposited by glacially fed streams. Includes sediment deposited into water bodies adjacent to glacier. GeMS Evaporitic rock Sedimentary rock, composed primarily of minerals produced by evaporation of saline solution. Examples include gypsum, anhydrite, other diverse sulfates, halite (rock salt), primary dolomite, and rocks composed of various nitrates and borates. GeMS Meta-felsic and intermediate rock Rock derived from preexisting felsic and intermediate-composition rocks by essentially solid-state, mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust.

GeMS Fine-grained, mafic-composition intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at shallow depth beneath Earths surface, thereby cooling quickly. Generally fine grained but may contain large mineral crystals (phenocrysts). Mostly found as tabular dikes or sills. Composed mostly of dark-colored minerals. Includes basaltic rock. GeMS Playa sediment Fine-grained clastic sediment and evaporitic salts, deposited in ephemeral lakes in centers of undrained basins. Includes material deposited in playas, mud flats, salt flats, and adjacent saline marshes. Generally interbedded with eolian sand and with lacustrine sediment deposited during wetter climatic periods; commonly intertongues upslope with sediment deposited by alluvial fans. GeMS Alluvial sediment, mostly fine-grained Unconsolidated material deposited by streams or other bodies of running water as sorted or semisorted sediment in streambed, or on its floodplain or delta, or as cone or fan at base of mountain slope. Sediment is mostly silt and clay but may also contain some sand and gravel. GeMS Mafic-composition air-fall tephra Fragments of volcanic rock and lava, of various sizes, carried into the air by explosions and by hot gases in eruption columns or lava fountains; known as tephra. As tephra falls to ground, with increasing distance from volcano, average size of individual rock particles and thickness of resulting deposit decrease. Because of their low silica content and resulting low viscosity, parental magmas tend to erupt gently as lava flows, and so these deposits are uncommon. Includes basalt; rocks are commonly dark-colored. GeMS Carbonate sediment Sediment formed by biotic or abiotic precipitation from aqueous solution of carbonates of calcium, magnesium, or iron (for example, limestone, dolomite). GeMS Iron-rich sedimentary rock Sedimentary rock, in which at least half (by volume) of observed minerals are iron bearing (hematite, magnetite, limonite group minerals, siderite, iron sulfides). GeMS Sandstone and mudstone Sandstone and mudstone (including shale and siltstone), in approximately equal (or unspecified) proportions. GeMS Debris flows, landslides, and other localized mass-movement sediment Sediment formed by relatively localized, downslope transport of particles or clasts produced by weathering and breakdown of underlying rock, sediment, and (or) soil. Composed of poorly sorted and poorly stratified material that ranges in size from clay to boulders. Speed of downslope transport ranges from rapid to imperceptible. GeMS Volcanic mass flow Volcanic deposits formed by mass movement (for example, debris avalanches, debris flows, lahar deposits), in many cases triggered by volcanic eruption. Debris avalanches that occur on volcanoes clearly without eruptive trigger may be classified as sedimentary (for example, as Debris flows, landslides, and other localized mass-movement sediment). GeMS Dolomite Carbonate sedimentary rock, consisting chiefly of dolomite. Although dolostone is the proper analog to limestone, it has not often been applied to dolomitic units. GeMS Deformation-related metamorphic rock Rock derived from preexisting rocks by essentially solid-state mineralogical, chemical, or structural changes in response to strong deformation, commonly in association with marked changes in temperature, pressure, and (or) chemical environment. Generally forms in narrow, planar zones of local deformation (for example, along faults); characterized by foliation or alignment of mineral grains. Includes mylonite and cataclasite. GeMS Loess Silty sediment, deposited by wind, commonly near glacial margin. GeMS Ice-contact and ice-marginal sediment, mostly fine-grained Mostly silt- and clay-sized particles or clasts, with lesser amounts of sand and gravel, derived from rock or preexisting sediment that has been eroded and transported by glaciers. As glacier melted, material was deposited by running water essentially in contact with glacial ice or was transported and deposited by glacially fed streams. Includes sediment deposited into water bodies adjacent to glacier. GeMS Coastal zone sediment, mostly coarse-grained Mostly sand, silt, and gravel, deposited on beaches, in dunes, and in shallow-marine and related alluvial environments. GeMS Marine sediment, mostly fine-grained Mostly clay- and silt-sized sediment, deposited in relatively deep, quiet water, far removed from areas where coarser grained clastic sediments are washed into marine environment. Includes sediment derived from marine organisms. GeMS Carbonate rock Sedimentary rock, consisting chiefly of carbonate minerals such as limestone or dolomite. GeMS Felsic-composition lava flows Lateral, surficial outpourings of molten lava from vent or fissure; also, solidified bodies of rock that form when they cool. Because of their high silica content and resulting high viscosity, parental magmas tend to erupt explosively, and so these deposits are uncommon. Includes fine-grained, light-colored rock with rhyolitic, dacitic, trachytic, and latitic composition. GeMS Coastal zone sediment, mostly fine-grained Mostly clay and silt, deposited in lagoons, tidal flats, backbarriers, and coastal marshes. GeMS Alluvial sediment, mostly coarse-grained Unconsolidated material deposited by streams or other bodies of running water as sorted or semisorted sediment in streambed, or on its floodplain or delta, or as cone or fan at base of mountain slope. Sediment is mostly sand, gravel, and coarser material but may also contain some silt and clay. GeMS Schist and gneiss, of sedimentary-rock origin Foliated rock derived from preexisting sedimentary rocks by essentially solid-state mineralogical, chemical, or structural changes in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Includes schist (characterized by such strong foliation or alignment of minerals that it readily splits into flakes or slabs) and gneiss (characterized by alternating, irregular bands of different mineral composition). Mostly formed from fine-grained material such as mudstone. GeMS Rock and sediment Various rocks and sediment, not differentiated. GeMS Sedimentary rock Consolidated material (rock) composed of particles transported and deposited by gravity, air, water, or ice, or accumulated by other natural agents operating at Earths surface, such as chemical precipitation or secretion by organisms. Does not here include sedimentary material directly deposited as result of volcanic activity. GeMS Metaigneous rock Rock derived from preexisting igneous rocks and altered by essentially solid-state, mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, shear stress, and (or) chemical environment, generally at depth in Earths crust.

Intermediate in color and in mineral composition (between felsic and mafic igneous rock). Includes andesitic rock. GeMS Other materials Other materials GeMS Marine sediment, mostly coarse-grained Mud, sand, and gravel eroded from rocks and sediment on land, transported by streams, and deposited in marine deltas and basins. Mostly siliceous in composition.

Includes shale and siltstone. GeMS Contact-metamorphic rock Altered rock that originated by local processes of thermal metamorphism, genetically related to intrusion and extrusion of magmas and taking place at or near contact with body of igneous rock.

GeMS Mostly sandstone Mostly sandstone, interbedded with other sedimentary rocks that locally may include conglomerate and finer grained clastic rocks (mudstone), carbonates, and (or) coal. GeMS Sand and gravel of unspecified origin Sediment composed mostly of sand and (or) gravel, formed by weathering and erosion of preexisting rocks or minerals; eroded particles or clasts are transported and deposited by gravity, air, water, or ice. GeMS Felsic-composition pyroclastic flows Hot ash, pumice, and rock fragments erupted from volcano or caldera. Material moves downslope commonly in chaotic flows; once deposited, hot fragments may compact under their own weight and weld together. Because of their high-silica content and resulting high viscosity, parental magmas tend to erupt explosively. Includes rhyolite, dacite, trachyte, latite; rocks are commonly light-colored. GeMS Mass movement sediment Sediment formed by downslope transport of particles or clasts produced by weathering and breakdown of underlying rock, sediment, and (or) soil. Composed of poorly sorted and poorly stratified material that ranges in size from clay to boulders. Includes colluvial, landslide, talus, and rock-avalanche deposits. GeMS Colluvium and other widespread mass-movement sediment Sediment formed by slow, relatively widespread, downslope transport of particles or clasts produced by weathering and breakdown of underlying rock, sediment, and (or) soil. Composed of poorly sorted and poorly stratified material that ranges in size from clay to boulders. GeMS Mafic-composition lava flows Lateral, surficial outpourings of molten lava from vent or fissure; also, solidified bodies of rock that form when they cool. Low-silica parental magmas have low viscosity and tend to form extensive sheets that have generally low relief. Includes basaltic shield volcanoes, which may become very large (for example, in Hawaii). Composed of fine-grained, dark rocks, including basaltic. GeMS Sediment Unconsolidated material (sediment) composed of particles deposited by gravity, air, water, or ice, or as accumulated by other natural agents operating at Earths surface such as chemical precipitation or secretion by organisms. Does not include sedimentary material directly deposited as a result of volcanic activity. GeMS Meta-carbonate rock Rock derived from preexisting carbonate sedimentary rocks and altered by essentially solid-state mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, deformation, and (or) chemical environment, generally at depth in Earths crust. Characterized by recrystallization of carbonate minerals in source rock. Includes marble (for which preexisting rock was dominantly limestone or other rock composed of calcite), dolomitic marble, meta-dolostone, and meta-dolomite (for which preexisting rock contained appreciable amount of magnesium). GeMS Igneous rock Rock and fragmental material that solidified from molten or partly molten material (magma). GeMS Coal and lignite Organic-rich sedimentary rock, formed from compaction and alteration of plant remains. Coal is consolidated, harder, black rock. Lignite is semiconsolidated, brown to black, earthy material that may contain large particles of recognizable plant parts and tends to crack upon drying. GeMS Lacustrine sediment Mostly well-sorted and well-bedded material that ranges in grain size from clay to gravel, deposited in perennial to intermittent lakes. Much of sediment is derived from material eroded and transported by streams. Includes deposits of lake-marginal beaches and deltas. GeMS Clastic sediment Sediment formed by weathering and erosion of preexisting rocks or minerals; eroded particles or clasts are transported and deposited by gravity, air, water, or ice. GeMS "Made" or human-engineered land Modern, unconsolidated material known to have human-related origin. GeMS Coarse-grained, intermediate-composition intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at some depth beneath Earths surface, thereby cooling slowly enough for mineral crystals to grow large enough to be visible to naked eye. Intermediate in color and in mineral composition (between felsic and mafic igneous rock). Includes dioritic rock. GeMS Quartzite Rock derived from preexisting quartz-rich sedimentary rocks (commonly sandstone) and altered by essentially solid-state mineralogical, chemical, or structural changes, in response to marked changes in temperature, pressure, shear stress, and (or) chemical environment, generally at depth in Earths crust. GeMS Ultramafic intrusive igneous rock Rock that solidified from molten or partly molten material (magma) at some depth beneath Earths surface, thereby cooling slowly enough for mineral crystals to grow large enough to be visible to naked eye. Composed almost entirely of mafic minerals (for example, hypersthene, augite, olivine). GeMS Lava flows Lateral, surficial outpourings of molten lava from vent or fissure; also, solidified bodies of rock that form when they cool. Composed generally of fine-grained, dark-colored rocks (for example, basalt), which tend to form extensive sheets that have generally low relief, except in vent areas where cinder cones or shield volcanoes may form. Includes basaltic shield volcanoes, which may become very large (for example, Hawaii). GeMS Intermediate-composition air-fall tephra Fragments of volcanic rock and lava, of various sizes, carried into the air by explosions and by hot gases in eruption columns or lava fountains; known as tephra. As tephra falls to ground, with increasing distance from volcano, average size of individual rock particles and thickness of resulting deposit decrease. Parental magma commonly erupts from stratovolcanoes as thick lava flows but also can generate strong explosive eruptions to form pyroclastic flows. Includes rocks that are, in color and mineral composition, intermediate between felsic and mafic rocks (for example, andesite). GeMS Sandstone Sedimentary rock, composed predominantly of particles or clasts derived by erosion and weathering of preexisting rock; consists mostly of sand-sized particles, with or without fine-grained matrix of silt or clay. GeMS Glacial till, mostly silty Mostly unsorted and unstratified material, generally unconsolidated, deposited directly by and underneath or adjacent to glacier without subsequent reworking by meltwater. Consists of heterogeneous mixture of clay, silt, sand, gravel, and boulders, ranging widely in size and shape. Relatively loamy (silty) in texture.
