Quaternary Geology of Bartholomew County (Azalia quadrangle)

Status Start Date End Date Locations
completed Oct 1, 2014 Sep 30, 2015 Bartholomew, Jackson, Jennings
Director: Nancy Hasenmueller
Other Researchers: Walter Hasenmueller, Barbara Hill, Matthew Johnson, Drew Packman, Robin Rupp, Kevin Russell, Henry Loope
Funding: U.S. Geological Survey (USGS) - Great Lakes Geologic Mapping Coalition
Issue: Water resources, development along transportation corridors, and mineral resource assessment are planning issues in Bartholomew County that are closely linked to the scientific interpretation of unconsolidated (glacial) sediments in the region.
Objective: This study will produce a detailed Quaternary geologic map of the Azalia 7.5-minute quadrangle with a cross section and detailed descriptions of map units.
Approach: An existing database of public domain geologic data for Bartholomew County will be refined by adding data from project drilling and field work. In addition, laboratory work will provide physical characterization of units used for identification and correlation of Illinoian and Wisconsin Episode glacial sediments. Quaternary geologic map units will be identified and standardized in the project database. Software will be used to aid in correlation of units in the subsurface and to construct a 3-D model of the Quaternary geology in the project area and generate the map and cross section products.
Products: Preliminary Quaternary geologic map of the Azalia 7.5-minute quadrangle, Indiana: Indiana Geological Survey Open-File Study 15-08
Benefits: The detailed maps and cross sections that will result from this project will help Bartholomew County planners address issues relating to water and mineral resources in the project area. The detailed mapping will facilitate production of a 1:48,000-scale Quaternary geologic map of Bartholomew County.
