Preliminary geologic map of the Calabasas 7.5' quadrangle, southern California: A digital database

This Open-File report is a digital geologic map database. 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 and
sources of geologic mapping consult Yerkes and Campbell (1993).
More specific information about the units may be available in the
original sources.
