Preliminary geologic map of the Hollywood 7.5' quadrangle, Southern California: a digital database
[摘要] This Open-File report is a digital geologic map database. This pamphlet serves to introduce and describe the digital data. There is no paper map included in the Open-File report.This digital map database is compiled from previously published sources combined with some new mapping and modifications in nomenclature. The geologic map database delineates map units that are identified by general age and lithology following the stratigraphic nomenclature of the U. S. Geological Survey. For detailed descriptions of the units, their stratigraphic relations, sources of geologic mapping, and data on exploratory wells consult Yerkes (1997), and Yerkes and Showalter (1990). More specific information about the units may be available in the original sources.
