Salinian Block
The Salinian Block or Salinian terrane is a geologic terrane which lies west of the main trace of the San Andreas Fault system in California. It is bounded on the south by the Big Pine Fault in Ventura County and on the west by the Nacimiento Fault. It was named for the Salinas Valley in Monterey County, California. Geology The Salinian Block is largely granitic, in accordance with its continental crustal origin. This composition contrasts sharply, and paradoxically, with much of the crust to its east, which is sedimentary and oceanic in origin. The block's granitic core, fragments of the batholith of the Peninsular Ranges, shares its origins with the Sierra Nevada mountains far to the east. During the past 30 million years the North American Plate has been overriding the East Pacific Rise and transform faulting along the developing San Andreas fault zone. Successive "stretched out" slivers of the Sierra Nevada - the Peninsular Batholith - have been and currently still are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transform Fault
A transform fault or transform boundary, is a fault (geology), fault along a plate boundary where the motion (physics), motion is predominantly Horizontal plane, horizontal. It ends abruptly where it connects to another plate boundary, either another transform, a spreading ridge, or a subduction, subduction zone. A transform fault is a special case of a ''strike-slip fault'' that also forms a plate boundary. Most such faults are found in oceanic crust, where they accommodate the lateral offset between segments of Divergent boundary, divergent boundaries, forming a zigzag pattern. This results from oblique seafloor spreading where the direction of motion is not perpendicular to the trend of the overall divergent boundary. A smaller number of such faults are found on land, although these are generally better-known, such as the San Andreas Fault and North Anatolian Fault. Nomenclature Transform boundaries are also known as conservative plate boundaries because they involve no addit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of San Luis Obispo County, California
Geology (). is a branch of natural science concerned with the Earth and other astronomical objects, the rocks of which they are composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface and the processes that have shaped that structure. Geologists study the mineralogical composition of rocks in order to get insight into their history of formation. Geology determines the relative ages of rocks found at a given location; geochemistry (a branch of geology) determines their absolute ages. By combining various petrological, crystallographic, and paleontological tools, geologists are able to chronicle the geological history of the Earth as a whole. One aspect is to demonstrate the age of the Earth. Geology provides evidence for plate tectonics, the evolutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Terranes
In geology, a terrane (; in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or " sutured" to crust lying on another plate. The crustal block or fragment preserves its distinctive geologic history, which is different from the surrounding areas—hence the term "exotic" terrane. The suture zone between a terrane and the crust it attaches to is usually identifiable as a fault. A sedimentary deposit that buries the contact of the terrane with adjacent rock is called an overlap formation. An igneous intrusion that has intruded and obscured the contact of a terrane with adjacent rock is called a stitching pluton. There is also an older usage of the term ''terrane'', which described a series of related rock formations or an area with a preponderance of a particular rock or rock group. Overview A tectonostratigraphic terrane did not necessarily originate as an independent microplate, since it may not contai ...

Point Reyes National Seashore
Point Reyes National Seashore is a park preserve located on the Point Reyes, Point Reyes Peninsula in Marin County, California. As a national seashore, it is maintained by the US United States National Park Service, National Park Service as an important nature preserve. No other park in the world hosts breeding hoofed megafauna (elk) and marine megafauna (elephant seal, elephant and other seals). Some existing agricultural uses are allowed to continue within the park. Clem Miller, a US Congressman from Marin County, California, Marin County, wrote and introduced the bill for the establishment of Point Reyes National Seashore in 1962 to protect the peninsula from development which was proposed at the time for the slopes above Drake's Bay. About half of the national seashore is protected as wilderness. History The Native American Coast Miwok lived in the area for thousands of years, in villages of seventy five to several hundred people. The Coast Miwok developed an economy of h ...

Julia Pfeiffer Burns State Park
Julia Pfeiffer Burns State Park is a state park in California, 12 miles south of Pfeiffer Big Sur State Park on California's Pacific coast. A main feature of the park is McWay Falls, which drops over a cliff of into the Pacific Ocean. The park is also home to Sequoia sempervirens, redwoods which are over 2,500 years old. The park is named after Julia Pfeiffer Burns, a respected resident and rancher in the Big Sur region in the early 20th century, who lived in the area for much of her life until her death in 1928. The park was established in 1962. Location and history Saddle Rock Ranch Christopher and Rachel McWay homestead principle, homesteaded the property in the late 1870s. In 1924, former U.S. House of Representatives, U.S. Representative Lathrop Brown and his wife Hélène were seeking an isolated point on the coast where they could build a home. They took a horse and mule trip to the Big Sur area and found Saddle Rock Cove where a waterfall poured over the ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
