Abstract:

Jadeitite is a kind of jadeite aggregates. The primary jadeitite deposits were formed during the collision between Indian plate and Eursian plate. The ultrabasic rocks intruded as dikes along faults, and underwent low-grade metamorphism under a compresso-shear stress. The deposits occur as veins in the serpentinized peridotite. The formation of jadeite has no genesis with ultrabasic rocks, only coexisting in location. The post-mineralization preservation plays a vital role in the values. Good quality jadeitites are always located at the upper to top of ultrabasic rocks, and also are found in alluvium by erosion. This paper discusses the depreciation-proof nature of jadeitite under the global financial crisis.
