Lithology and Stratigraphy This subsection is mostly on the
Salinian Block, between the San Andreas and Nacimiento faults.
It is predominantly Mesozoic granitic and pre-Cretaceous
metamorphic rocks. There is some Cretaceous sedimentary rock of
the Great Valley Sequence, considerable Miocene marine
sediments, and some other Tertiary sediments. Also, there are
some rocks of the Franciscan Complex on the southwest edge where
the subsection crosses the Sur-Nacimiento fault zone. This is a
subsection of northwest trending mountains with rounded ridges,
steep sides, and narrow canyons. Remnants of marine terraces are
present along the coast and nonmarine terraces on the Monterey
Peninsula, but they are not extensive. The subsection elevation
range is from sea-level up to 5862 feet on Junipero Serra Peak.
Mass wasting and fluvial erosion are the main geomorphic
processes. The soils are mostly shallow Typic Xerorthents, Entic
and Pachic Ultic Haploxerolls, and Pachic Argixerolls. On
Cretaceous and Miocene sedimentary
