Mining in the State Line Serpentine Barrens

The main mineral extracted from the Serpentine Barrens has been chromite, a chromium ore. Other minerals mined include feldspar, magnesite, soapstone, corundum, and talc. The serpentine rock has also been used for building. Local mines for building and road stone included the Dunlap, White Barrens, and the Carter, Reynolds & Griest quarries.

State Line Serpentine Barrens The Nature Conservancy

Located along the Maryland-Pennsylvania border, the State-Line Serpentine Barrens contains some of the last major remnants of serpentine grassland in eastern North America. The thin soils covering this light-green bedrock contain high levels of nickel, chromium and other metals that prove toxic to most plants and animals. This habitat, while

Serpentine soil Wikipedia

Serpentine soil is an uncommon soil type produced by weathered ultramafic rock such as peridotite and its metamorphic derivatives such as serpentinite.More precisely, serpentine soil contains minerals of the serpentine subgroup, especially antigorite, lizardite, and chrysotile or white asbestos, all of which are commonly found in ultramafic rocks. The term "serpentine" is commonly used to

Serpentine Plant Communities Barrens

In fact, serpentine barrens contain more narrow endemic plants than any other serpentine natural community in the Klamath-Siskiyou region; and as such, the most rare plants (Jimerson, et. al. 1995). Represented plant genera associated with the harshest of serpentine communities include Arabis, Eriogonum, Sedum, and Streptanthus.

Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.The primary operations are comminution and concentration, but there are other important operations

Borrowed alleles and convergence in serpentine adaptation

Jul 19, 2016· Serpentine barrens offer powerful venues for the study of multitrait adaptations. Soils at these sites feature dramatically skewed elemental contents, phytotoxic levels of heavy metals, drought risk, and very poor mineral nutrition (1 –3).A defining characteristic of serpentine soils is a greatly reduced Ca:Mg ratio along with low K, N, and P, resulting in severe ion homeostasis challenges

San Benito Mountain is the highest mountain in the Diablo Range of California.The highest point is at an elevation of 5,267 feet (1,605 m). The rock is composed of asbestos (chrysotile), an ultramafic rock. It weathers to produce serpentine soils with characteristically low levels of nutrients like nitrogen, phosphorus, potassium, and calcium, and high levels of magnesium and heavy metals
