From the introduction to the report:
This report, digital geodatabase, and the accompanying set of geologic map plates were prepared to provide an updated and spatially accurate geologic framework for the southwestern Oregon coast between Crook Point and Port Orford in westernmost Curry County (Figure 1; map plates). The preliminary geologic mapping summarized here represents one part of a multi-year project initiated in 2012 to map the southwestern Oregon coast from the California border north to Coos Bay. The project is a high priority of the Oregon Geologic Map Advisory Committee and was supported in part during 2012 and 2013 by the U.S. Geological Survey (USGS) STATEMAP component of the National Cooperative Geologic Mapping Program under assistance award G12AC20184. Matching funds were provided by the Oregon Department of Geology and Mineral Industries (DOGAMI). The core product of this study is an Esri ArcGIS™ ArcMap™ 10 format geodatabase that combines new and existing mapping in a digital format consistent with the digital statewide Oregon Geologic Data Compilation database (OGDC-5, Ma and others, 2009). The geodatabase contains detailed spatial information about geologic polygons and structures and basic data about each geologic unit such as age, lithology, mineralogy, and structure. The geodatabase is supported by this report, which describes the geology in detail, and by digital appendices with geochemical, geochronological, structural, and subsurface data interpreted from water wells. This publication also includes four preliminary geologic maps (see map plates) at a scale of 1:24,000 to show the distribution of contrasting lithologies, critical structural relationships, and corresponding geologic hazards in the study area. The geologic maps refine our understanding of geologic conditions along the southwestern Oregon coast that control the distribution, quantity, and quality of groundwater resources, the distribution of terrain susceptible to landslides and seismic hazards, and areas of potential aggregate and other mineral resources. The database provides a basis for future geologic, geohydrologic, and geohazard studies for the area.
