This ultrabasic massif is assigned to magnesian ultramafic massif of Alpine type. In these ultrabasic recks, the major minerals are forsterite, enstatite, diopsite and chrome spinel The rocks are very fresh, and therefore, texture and structure characteristics of compression during tectonic movement are commonly observed. Undulatory extinction, polysynthetic twin, kink band structure, enlongation and contortion of olivine and orthopyrexene crystals, radiating cracks occurring around the chrome spinels and so forth are commonly observed phenomena. All these features show that the massif was under constant action of tectonic compression during its evolution process and after it was basically consolidated. It is reasonable to consider that the tectonic compression was related to plate collision between the Indian and Eurasian plates.展开更多
