Every rock is composed of one or more minerals. Peridotite composition which can be further divided into mineral and compound content. The Peridotite mineral content includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene.
Its compound content includes Ca, Fe, Mg, Potassium, Silicon Dioxide, Sodium, Titanium Dioxide. You can also check out Properties of Peridotite.
Transformation of Peridotite
Every rock on earth undergoes transformation process. Peridotite is a type of Igneous Rocks. Transformation of Peridotite takes place in three steps- Metamorphism, Weathering and Erosion.
- Metamorphism of Peridotite:- Metamorphism is change in arrangement of minerals and texture in the pre-existing rocks. Peridotite rock undergoes metamorphism. Unlike in formation of Peridotite, the rock does not melt into liquid magma. Peridotite undergoes burial metamorphism, cataclastic metamorphism, contact metamorphism, hydrothermal metamorphism, impact metamorphism and regional metamorphism.
- Weathering of Peridotite:- The breaking down of rocks when they come in contact with the Earth's atmosphere, ecology and water is called as weathering. Talking about weathering of Peridotite, this rock undergoes weathering. Weathering of Igneous rocks leads to formation of Sedimentary rocks. Weathering is further classified as chemical and mechanical weathering. Peridotite undergoes biological weathering, chemical weathering and mechanical weathering.
- Peridotite Erosion:- After formation of Peridotite, let’s move on to Peridotite Erosion. The weathered small fragments of rock are carried from one place to other by a process called erosion. Peridotite rock undergoes Erosion. Erosion is one of the important aspects in the life cycle of a rock. Peridotite undergoes chemical erosion.
