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.

It is still being mined for dimension stone at the Cedar HillAbout The State Line Serpentine Barrens - the2nomads,The Barrens used to be known as the State Line Mining district due to the Chromium mining that took place at various sites, mainly in the 19th century. The sun-baked conditions on bare serpentine rock and gravel create desert-like habitat for rare and unusual plant species that are specially adapted to withstand heat and drought. However, while lacking nutrients, this habitat supports numerous species—many

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 refer to both the soilState 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 lacking nutrients, supports unusual, rare or endangeredMining in the State Line Serpentine Barrens,In other serpentine areas, such as those in Maryland, Vermont, and Ontario, asbestos has been mined. The amounts of asbestos found in the State Line Serpentine Barrens are generally small and little or no commercial extraction has taken place. The main period of mining took place during the 19th century. Historical maps are available for viewing.

Serpentine barrens are a unique ecoregion found in parts of the United States in small but widely distributed areas of the Appalachian Mountains and the Coast Ranges of California, Oregon, and Washington. Species-rich archipelagos of communities comprise 1.5% of the state's land area. [specify] In California, 10% of the state's plants are serpentine endemics.Soldiers Delight - Maryland,Soldiers Delight Serpentine Barrens is located in the Soldiers Delight Natural Environmental Area in western Baltimore County. The barrens are underlain by serpentinite, a rock that contains very little quartz and aluminum-bearing minerals and consists mainly of serpentine. When serpentinite weathers most of the rock dissolves leaving behind a thin, sand- and clay-poor soil which is easily,State Line Serpentine Barrens - Western Pennsylvania,,Nottingham Barrens, a managed serpentine barrens owned by Chester County, supports 29 rare plant and 38 rare animal species. Habitat Threats and Management . The serpentine barrens are mosaics of grasslands, pitch pine woodlands and scrub habitat which were historically dependent upon fire and grazing to remain open.

Serpentine Plant Communities - Barrens

Serpentine barrens occur as small, one to two acres or larger, openings surrounded by serpentine conifer or woodland communities. Outcrops of exposed bedrock are commonly found in nested in the barren community. Serpentine barrens represent the harshest serpentine community. The soils are extremely thin and rocky lying directly upon the parent material (most commonly serpentinite).
