KGS Researchers Present Geologic Mapping and 3D Research funded by the USGS
KGS researchers recently attended two virtual meetings focused on geologic mapping. William Andrews, Anna Pearson, Doug Curl, and Nolan Whitt gave talks at the Digital Mapping Techniques meeting coordinated by the U.S. Geological Survey and hosted by the Illinois State Geological Survey. William Andrews and Anna Pearson also presented at the Geologic Mapping Forum hosted by the University of Minnesota.
Through a live demonstration, they showed the work they have accomplished since August 2021 for the statewide 3D mapping project. According to Andrews, “We’re focusing on database development at this stage of the project because we can easily make models if we have a good database. Our overall goal is to develop a database of subsurface geologic information for Kentucky that is flexible and easily updated and accessed. This database will provide foundational support for future geological research in Kentucky and for applied projects led by KGS researchers or stakeholders.” KGS researchers used available published data to build a foundation for the 3D framework including lidar-derived land surface data, faults, and stratigraphic contact surfaces from geologic maps, carbon sequestration project data, coal assessments, and other previous subsurface projects. Curl and Whitt presented preliminary work to improve the understanding of stratigraphic relationships in the statewide 2D geologic map database, which will also help enhance the overall Kentucky 3D framework. Future work includes a detailed set of reference well logs from across the state.
This project will serve the entire state of Kentucky. KGS received support from USGS grants under the StateMap, Earth MRI, and National Geologic Map Database to pursue the work. The StateMap award for 2021-2022 is the largest KGS has received in the 29-year history of the StateMap program. Collaborations with staff at ESRI, MATLAB, the U.S. Geological Survey, several state geological surveys, and especially Melony Barrett at the Illinois Geological Survey have helped advance these projects. Besides Andrews, Pearson, Curl, and Whitt, research team members include Devan Robinson, Dibya Koirala, Dave Harris, and John Hickman.
