Bedrock Geology of Maine (1:500,000) Shapefiles and KMZ files

Basic Information
Author: Tucker, Robert D.
Description:The Bedrock Geology maps bedrock geology units and major faults for Maine at 1:500,000 scale. The data were developed by the Maine Geological Survey from the Bedrock Geologic Map of Maine (Osberg, Hussey, and Boone, 1985). The data for this map were scanned off 1:500,000 scale mylars by the United States Geological Survey in 1987. The original bedrock unit codes were added by the J.W. Sewall Co. (1990) for the Maine Low-Level Radioactive Waste Authority. In 1994, staff at the Maine Geological Survey identified and added codes for major bedrock faults. Bedrock unit codes assigned to this dataset are available in comma delimited text and .dbf format from the Maine GIS Data Catalog ( and KMZ files showing bedrock geology of the state of Maine at a scale of 1:500,000.
