north of the San Francisco Bay, plate motion on the San Andreas fault system is almost entirely parallel to the trend of the fault (DeMets et al., ) (Fig. 1A). Rather than transpression-driven or subduc-tion-related uplift, the underlying cause for the formation of the Coast Ranges is more likely processes associated with the passage of theFile Size: 1MB. The geology you see around San Francisco is the result of forces along the Pacific and North American plates. Today, the Pacific Plate is slowly creeping north past the North American Plate, forming the San Andreas fault system. San Francisco Bay was created by .
The San Francisco Bay region is one of the premier sites in the world to see the effects on land of plate tectonics. Now part of a transform plate boundary, it was for much of the Mesozoic and early Cenozoic part of a convergent plate boundary. Start studying Earth Science California Geology.

The Golden Gate is a strait on the west coast of North America that connects San Francisco Bay to the Pacific Ocean. It is defined by the headlands of the San Francisco Peninsula and the Marin Peninsula, and, since , has been spanned by the Golden Gate nates: 37°49′N °30′W / °N . Contemporary seismicity in the northern California Coast Ranges from San Francisco Bay to the town of Healdsburg and east of the seismically quiescent North Coast segment of the San Andreas fault is generally confined to the intensely deformed Santa Rosa block relative to the adjacent Sebastopol by: 7.

The hills of the Coast Ranges immediately north of San Francisco occupy three north-westward-trending areas which are separated by the San Andreas fault and northern extension of the Haywards fault system. Each area is composed of distinct groups of rock formations. Geology of the Coast Ranges Immediately North of the San Francisco Bay Region, California (The Geological Society of America.

An excellent book for anyone interested in the geology of the San Francisco Bay Region (which has some of the most exciting and diverse geology anywhere).
I especially like that it's organized by area, and at the end of each chapter tells you places to go to see the geology of that by: This book is for San Francisco Bay Area residents and visitors who want to explore the geologic world of this spectacular area, to learn about its shapes, colors, and rocky foundations.

the coast between Orange County and the San Francisco region. The appearance of the basins may have signaled the passage of what is now coastal southern and central California over the spreading zone.
The rocks formed in these basins (Monterey Formation) are composed mainly of material derived from marine organisms, rather than terrestrial. Evolution of Western North America Illustrated.
Below are a series of generalized geologic cross sections following a transect between San Francisco (to the west) and Denver (to the east)—a distance of about 1, miles (1, kilometers).
On the right are brief highlights in. The Coast Ranges are subdivided into sections including, from north to south, the Oregon Coast Ranges, the Kamath Mountains (straddling the Oregon California border), the Northern Coast Ranges (extends southward from Crescent City, California the Northern San Francisco Bay Area), the Southern Coast Ranges (between San Francisco and Santa Barbara), the Transverse Ranges (between Santa Barbara and Los Angeles.

San Francisco Bay as we know it is a very young landform in geologic time. In this segment you’ll learn that: the west coast of North America has changed dramatically over time.
the Bay with which we are familiar was created j years ago. San Francisco Bay is a flooded river canyon thatFile Size: KB. The Sacramento is the only river that cuts through the Coast Range to the ocean, so it must have been flowing before the range emerged so that it could erode the rocks as quickly as they rose.
The San Francisco Bay is feet deep in places so the Golden Gate is like a drain in a bathtub constantly scoured by a huge volume of water that flows in and out of a tiny opening as the tides change.
The Northern Coast Ranges are a section of the California Coast Ranges. They run parallel to the Pacific Coast from the North San Francisco Bay Area to coastal Del Norte County. The Klamath Mountains, including the Siskiyou Mountains sub-range, lie to the north and northeast. The Southern Coast Ranges lie to the : Mount Linn.
volcanic fields. The Coast Ranges are subparallel to the active San Andreas Fault. The San Andreas is more than miles long, extending from Pt. Arena to the Gulf of California. West of the San Andreas is the Salinian Block, a granitic core extending from the southern extremity of the Coast Ranges to the north of the Farallon Islands.
COAST File Size: 2MB. The best known geologic feature in northern California is the San Andreas fault (Oakshott, ), which extends north along the coast from San Francisco and ends at the "Triple Junction" offshore of Cape Mendocino.
The Triple Junction is where the American Plate, Pacific Plate and the Gorda Plate meet. In the California Coast Ranges east of San Francisco, post Ma folding and erosion of the Mount Diablo anticline have created unusual three-dimensional exposures of late Mesozoic-Cenozoic Author: Will Elder.
