Mineralogy of Hemipelagic Basin Sediments, California Continental Borderland

Abstract

Minerals in Holocene and late Pleistocene basin sediments of the northern California Continental Borderland are derived from local sources, and in minor amounts from wind- and current-borne sediment. Source, sea level fluctuations, differential settling, and sedimentation by floods control the distribution of the mineralogy. River-sediment mineralogy can be divided into northern sedimentary, central igneous-metamorphic, and southern batholithic suites. Analysis of cores reveal mineralogic variations that are largely controlled by sea-level fluctuations. Numerous well-sorted gray silt layers in Santa Barbara Basin appear to be flood-deposits that formed after unusually heavy storms, such as occurred in 1969.
