Clinopyroxene mineral Britannica
WebClinopyroxene is a major host for sodium, calcium, chromium, and titanium in mantle xenoliths and shows extensive solid solution toward orthopyroxene and/or garnet at high P and T in the mantle ( Boyd, 1969, 1970; Brey and Köhler, 1990 ). The Mg# of clinopyroxene is usually slightly greater than that of coexisting olivine, due to a KD … Webclinopyroxene in XPL. inclined extinction second order interference colors. hornblende (amphibole) in PPL. moderate to high relief pleochroic splintery appearance. hornblende … WebSimple or Lamellar.
