Title
A name given to the resource
(FR) Sedimentary and Igneous Franciscan Assemblage Suite -- California
Description
An account of the resource
This 14 sample collection primarily consists of clastic sedimentary rocks with metamorphic and igneous components, representing a Franciscan Assemblage. This assemblage is indicative of a subduction zone along the California coast.
Contributor
An entity responsible for making contributions to the resource
Western Minerals, Inc. - Collection was supervised by Dr. Frederick C. Marshall, Assistant Professor of Geology at Principia College.
