Salinian block
The Salinian Block is a geological province located west of the main trail of the San Andreas Fault System in California . It is bounded to the south by the Big Pine Fault in Ventura County and to the west by the Nacimiento Fault.
The Salinian Block is made of hard granite according to its origin from the earth's crust with sharp contrast and paradoxically with most of the crust in the east, which in California has the most sedimentary and oceanic origins. The granite core or batholith shares its origin with that in the Sierra Nevada Mountains . The Salinian Block was the southern extension of the same granite catholite that forms the core of the Sierra Nevada, fractured and moving northwest due to the San Andreas Fault in a shape that has not yet been fully explained.
Today, the northern parts of the block such as Bodega Head , Point Reyes , the Farallon Islands and the picturesque coastal landscape of the Monterey Peninsula , e.g. B. can be visited at Pebble Beach .
The block was named after the Salinas Valley in California.
