The geology of California is highly complex, with numerous mountain ranges, substantial faulting and tectonic activity, rich natural resources and a history of both ancient and comparatively recent intense geological activity.
2 cze 2023 · The geological history of California spans billions of years, and is marked by various tectonic and geologic processes that have shaped the state’s landscape. From the formation of the Sierra Nevada to the movement of the San Andreas Fault, each region of the state has a unique geological history.
The First Attempts. Geologic mapping in California began about 180 years ago. The first geologic mapping in the State, done by Lieutenant Edward Belcher, a British naval officer, was a remarkably accurate geologic map of the Port of San Francisco.
For decades the Geologic Atlas of California (discussed in the next section) has been the primary source of regional-scale geologic maps in California. In an effort to keep the maps current, the CGS has been compiling a new series of Regional Geologic Maps (RGM), starting in 1981.
A geologic map is the principal tool of a geologist or engineer who either needs to convey or decipher information about the Earth’s surface. Geologic maps are used to interpret the structure, stratigraphy, mineralogy, paleontology, and the historical record of the Earth’s crust.
15 lut 2021 · This historically significant report provides an overview of the history, geology, geomorphology, geophysics, and seismology of the most well known plate-tectonic boundary in the world.
The California Geological Survey's interactive geological map allows users to identify the different rock types and fault lines throughout California. In addition to the web viewer, the GIS data can be downloaded for further use.
