On the other hand, the pyroxenite has a very high content of incompatible elements (e.g. Th or REE) due to abundant apatite; consequently their REE patterns are commonly similar to that of apatite. The A1 2 O 3 (2%) and TiO 2 (<0.4%) contents of diopside are very low, whereas the biotite (or phlogopite) is rich in TiO2 (3–4%).
