Explanation

It is also called ophiolite suite. It is the combination of magnesium iron ultramafic metamorphic rock with specific composition. The main rock assemblages include: serpentinite and serpentinite schist formed by serpentinite metamorphism; chlorite tremolite schist with metamorphic pillow structure formed by pyroxene metamorphism; The actinolite schist or amphibolites with metamorphic pores or almond structure formed by basalt metamorphism. Most of them are distributed in tectonic activity zones, mid ocean ridges, and plate collision zones. The minerals related to it are chromium, molybdenum, gold, nickel, etc. The serpentine commonly associated with ophiolite is an important non-metallic mineral.
