Abstract

In this paper the author seeks to describe the geological relations and properties of the more important clay producing areas in Riverside and Orange Counties, Southern California. As a result of his work he finds that the clays are found in a particular Tertiary formation, of Martinez age. They were deposited under continental conditions at the edge of a gradually encroaching sea. The clays are invariably associated with lignitic shales and coals and thus represent deposition in a humid, probably temperate climate under extremely reducing conditions.
