Dating topography of the sierra nevada
The character of the range is shaped by its geology and ecology. (million years) ago, and erosion by glaciers exposed the granite and formed the light-colored mountains and cliffs that make up the range.More than one hundred million years ago during the Nevadan orogeny, granite formed deep underground. The uplift caused a wide range of elevations and climates in the Sierra Nevada, which are reflected by the presence of five life zones.To select pages to copy: Price lists, contact information, and order forms are available on the Duplication Services Web site.Please use the following steps to determine whether you need to fill out a call slip in the Prints and Photographs Reading Room to view the original item(s).In some cases, a surrogate (substitute image) is available, often in the form of a digital image, a copy print, or microfilm.Your access to the NCBI website at gov has been temporarily blocked due to a possible misuse/abuse situation involving your site.
A robust finite-element code (Pecube) has been developed to solve the three-dimensional heat transport equation in a crustal/lithospheric block undergoing uplift and surface erosion, and characterized by an evolving, finite-amplitude surface topography.
The range is surrounded by a tectonically active zone on the west coast of North America, primarily in the state of California, with small portions lying within Nevada.
Currently to the west of the range lies a large transform plate boundary, the San Andreas Fault, which is still affecting the size and scope of the range today.
From the computed crustal thermal structure, the temperature history of rock particles that, following an imposed tectonic scenario, are exhumed at the Earth's surface, is derived.
These paths can then be used to compute apparent isotopic ages for a range of geochronometers.
