CLASTIC SEDIMENTARY ROCKS 



The most abundant and widespread of the Fran- 

 ciscan rock types are the clastic sedimentary rocks, 

 which in the Xew Almaden area amount to more than 

 two-thirds of the assemblage. Although the sedi- 

 mentary rocks are widely distributed throughout the 

 district, no single exposure serve- to show the variety 

 of rocks included in this single cartographic unit. 

 However, one easily accessible, and fairly representa- 

 tive, series of exposure is afforded by the roadcuts 

 along the first _> miles of State Highway IT south of 

 Los Gatos.
