Geologic Map of the Eminence Quadrangle, Shannon County, Missouri

The framework will be used to assess environmental impacts of lead and zinc mining in the Mark Twain National Forest on the hydrologic system of the Ozark National Scenic Riverways. The geology of the Eminence 7 1/2-minute quadrangle , Shannon County, Missouri was mapped from 1996 through 1997 as part of the Midcontinent Karst Systems and Geologic Mapping Project, Eastern Earth Surface Processes Team.

The map supports the production of a geologic framework that will be used in hydrogeologic investigations related to potential lead and zinc mining in the Mark Twain National Forest adjacent to the Ozark National Scenic Riverways (National Park Service). Digital geologic coverages will be used by other federal and state agencies in hydrogeologic analyses of the Ozark karst system and in ecological models. Bedrock, Quaternary , residual units, faults, and structural data are each stored in separate coverages.
