Quaternary Geology of Bartholomew County (New Bellsville and Columbus quadrangles)

Status Start Date End Date Locations
completed Oct 1, 2013 Sep 30, 2014 Bartholomew, Brown
Director: Nancy Hasenmueller
Other Researchers: Deborah DeChurch, Walter Hasenmueller, Matthew Johnson, Drew Packman, Robin Rupp, Kevin Russell, Henry Loope
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 detailed Quaternary geologic maps of the New Bellsville and Columbus 7.5-minute quadrangles with cross sections 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.

Preliminary Quaternary geologic map of the New Bellsville 7.5-minute quadrangle, Indiana: Indiana Geological Survey Open-File Study 14-02, scale 1:24,000.

Preliminary Quaternary geologic map of the Columbus 7.5-minute quadrangle, Indiana: Indiana Geological Survey Open-File Study 14-03, scale 1:24,000.
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.
