K-feldspar content of Jurassic and Cretaceous graywackes of northern Coast Ranges and Sacramento Valley, California K-feldspar content of Jurassic and Cretaceous graywackes of northern Coast Ranges and Sacramento Valley, California

Graywackes of Late Jurassic to Late Cretaceous age are the predominant rocks in the northern Coast Ranges and the western Sacramento Valley provinces in California. These graywackes are similar in appearance, but their content of K-feldspar, which can be readily estimated after selective staining, differs widely. Study of several hundred specimens indicates that K-feldspar content is...

Franciscan group in Coast Ranges and its equivalents in Sacramento Valley, California Franciscan group in Coast Ranges and its equivalents in Sacramento Valley, California

The Franciscan group is an assemblage of detrital and chemical sedimentary and volcanic rocks that crops out discontinuously in a structurally complex, northwesterly trending belt along the Coast Ranges of Cahfornia. On the east, along the west side of the Sacramento Valley, a thick section of detrital sedimentary rocks has been subdivided into the Knoxville, Paskenta, and Horsetown...
