The genetic relation between good-quality jadeite and microstructure
摘要
Abstract
Jadeite is the queen of jade. In the past, the study about this topic is concentrated in identification, composition and its trade. especially in studing the ‘B goods’ until recently, there are only few study in the generation and mechanism of jadeite which is a very important topic.The authors have attempted to shed light on reliving above the problem by microtexture and microstucture methods and summarize the research data made by our four doctor and master students. The results have demonstrated that the dynamic metamorphism has close relationship with jadeite quality. Cataclastic texture which came from brittle deformation made the jadeite quality bed, but the mylonitic texture which resulted from ductile deformation made the jadeite quality good. Under the condition of the low temperature, strong shear stress and high strain velocity, through the dislocation glide, sub grain and dynamic recrystallization, the ductile deformation made the jadeite grain fined, the crystal close mosaic, the different pores fill and the transparency good. The green jadeite was formed mainly as a result of the desalination of chromite.In general, the green color is distributed in the center place of ductile deformation area, the high stress is of great advantage to the concentration of chrome.关键词
