Geologic units containing Serpentinite
Serpentinite is formed by near to complete serpentinization of mafic to ultramafic rocks. Serpentinite can be formed wherever ultramafic rock is infiltrated by water poor in carbon dioxide. This occurs at mid-ocean ridges and in the forearc mantle of subduction zones. The final mineral composition of serpentinite is … 더 보기 Serpentinite is a rock composed predominantly of one or more serpentine group minerals, the name originating from the similarity of the texture of the rock to that of the skin of a snake. Serpentinite has been called … 더 보기 Decorative stone in architecture and art Serpentine group minerals have a Mohs hardness of 2.5 to 3.5, so serpentinite is easily 더 보기 • Hydrogen cycle – Hydrogen exchange between the living and non-living world • Nephrite – Variety of jade • Soapstone – Talc-bearing metamorphic rock 더 보기 Soil cover over serpentinite bedrock tends to be thin or absent. Soil with serpentine is poor in calcium and other major plant nutrients, but rich in elements toxic to plants such as 더 보기 Notable occurrences of serpentinite are found at Thetford Mines, Quebec; Lake Valhalla, New Jersey; Gila County, Arizona; Lizard complex, Lizard Point, Cornwall; and in localities in Greece, Italy, and other parts of Europe.
