WebOrthopyroxene is also found around clinopyroxene as granular exsolution. Large grains of Fe-Ti oxides occur within the interstitial space. Garnet (Grt) and quartz (Qtz) form at the contact of plagioclase and clinopyroxene. The product minerals are found as symplectite and/or corona rimming the reactants. 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 ). flir training center
