8 Metamorphic Minerals and Metamorphic Rocks

Minerals in high-grade ultramafic rocks are the same as the minerals in rocks of the mantle (where pressure and temperature are great). In effect, such rocks originated as high-grade metamorphic rocks. We saw photos of several examples in Chapter 6 (Figures 6.118, 6.119, and 6.120). 8.7 High-Pressure Rocks and Minerals
