FEDMAP Project Summary

Mancos Shale Landscapes: Science and Management of Black Shale Terrains, CR MRT


To understand black shale regions in the western United States both as sources of mineral riches and toxic environments.


Detailed geologic mapping and stratigraphic studies are being conducted on the Mancos Shale in the Gunnison Gorge National Conservation Area. Black shales can be both a source of mineral wealth (oil and gas) and a cause of environmental concern (sources of arsenic, selenium, chromium, and mercury). This project is providing applicable, scientifically valid information, including economic resource potential and environmental sensitivity that can be used to make informed land-use decisions for black shale regions.
