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. WebBlueschist-facies metamorphism is important in subduction zones, where high-pressure, relatively low-temperature mineral assemblages form. Glaucophane and lawsonite, both of which have a bluish color, are common minerals in this setting. In subduction zones, crustal fragments can be carried to great depths (>50 km), yet remaining at rather low ...
