This digital map database, compiled from new mapping by the authors, represents the general distribution of bedrock and surficial deposits of the Dixonville 7.5 minute quadrangle along the southeastern margin of the Oregon Coast Range and its tectonic boundary with Mesozoic terranes of the Klamath Mountains. Together with the accompanying text files as PDF (geol.pdf), it provides current information on the geologic structure and stratigraphy of the area covered. The database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U.S. Geological Survey. The scale of the source maps is 1:24,000. The spatial resolution (scale) of the database is 1:24,000...
