WebMay 31, 2024 · Blueschist is a common metamorphic rock of continental shields. Roofers use the rock schist to shingle roofs because its foliation, called schistosity, causes it to break in convenient size. Is tremolite toxic? The fibrous form of tremolite is one of the six recognised types of asbestos. Blueschist facies generally is considered to form under pressures of >0.6 GPa, equivalent to depth of burial in excess of 15–18 km, and at temperatures of between 200 and 500 °C.

WebUses of Blueschist Every rock is formed under different chemical, physical and biological conditions which results in formation of a wide and distinct group of minerals and hence they find applications in various fields. Rocks are hard, soft, permeable and impermeable. They are of various sizes and shapes, depending on the type of rock. WebBlueschist ( / ˈbluːʃɪst / ), also called glaucophane schist, is a metavolcanic rock [1] that forms by the metamorphism of basalt and rocks with similar composition at high pressures and low temperatures (200–500 °C (392–932 °F)), approximately corresponding to a depth of 15–30 km (9.3–18.6 mi).
