Rescue Lineament-Bear Mountains Fault Zone
The Rescue Lineament-Bear Mountains fault zone, in eastern California, is a series of co-axial faults located in the western foothills of the Sierra Nevada (mountain range).https://earthquake.usgs.gov/earthquakes/recenteqscanv/fault/197.html USGS . accessed 12.2.2010 The fault zone represents an ancient suture, the boundary where an ancient oceanic crustal block known as an exotic terrane, named by geologists the Smartville Block, collided with and attached to the North American Plate. Gold To the west of the ancient suture/fault zone the Mother Lode, of the California Gold Rush, was found in the Smartville Block's Ophiolite oceanic crust material.

Eastern California
Eastern California is a region defined as either the strip to the east of the crest of the Sierra Nevada or as the easternmost counties of California. Demographics According to the 2010 census, the population of the eastern border counties of California was 5,129,384. However, 4,224,851 (82.4%) lived in San Bernardino and Riverside counties, which are very large and whose populations are concentrated near Los Angeles and Orange counties to the southwest. Culture and history Eastern California's history differs significantly from that of the coastal regions and the Central Valley. Northeastern California is very sparsely populated (except for the area around Lake Tahoe): the three least-populated counties of California lie in the northeast. The area tends to be politically conservative, much like the rest of the rural Western United States. However, the counties of San Bernardino and Riverside form the 13th-largest metropolitan area of the United States, and El Dorado and Pla ...

Seismic Faults Of California
Seismology (; from Ancient Greek σεισμός (''seismós'') meaning "earthquake" and -λογία (''-logía'') meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. It also includes studies of earthquake environmental effects such as tsunamis as well as diverse seismic sources such as volcanic, tectonic, glacial, fluvial, oceanic, atmospheric, and artificial processes such as explosions. A related field that uses geology to infer information regarding past earthquakes is paleoseismology. A recording of Earth motion as a function of time is called a seismogram. A seismologist is a scientist who does research in seismology. History Scholarly interest in earthquakes can be traced back to antiquity. Early speculations on the natural causes of earthquakes were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE), Aristotle (c. 340 BCE), and Zhan ...

Geography Of Mariposa County, California
Geography (from Ancient Greek, Greek: , ''geographia''. Combination of Greek words ‘Geo’ (The Earth) and ‘Graphien’ (to describe), literally "earth description") is a field of science devoted to the study of the lands, features, inhabitants, and phenomena of Earth. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). Geography is an all-encompassing discipline that seeks an understanding of Earth and world, its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. One such concept, the Tobler's first law of geography, first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
