List of orthopyroxene minerals
Web22 jul. 2024 · Table 1 lists the possible dehydration melting reactions of crustal rocks. The dehydration of hydrous minerals in pelitic and felsic metamorphic rocks mainly relies on the presence of muscovite and biotite, while in intermediate and basic metamorphic rocks, it is mainly controlled by the existence of biotite and amphibole. Web12 mrt. 2024 · Orthopyroxene commonly forms rims around opaque oxide minerals (Fig. 2b). The Fe-Ti oxide minerals include magnetite and ilmenite (5–8%) and display exsolution textures. Magnetite and ilmenite occur as homogeneous suhedral to anhedral or skeletal grains or as interstitial aggregates between plagioclase and pyroxenes (Fig. 2b ).
