    • Abstract
  • Through the field survey of Myanmar jadeite jade, the microscope observation of a lot of jadeite jade thin sections and fluid inclusions and more than one hundred EPMA analysis, the hypothesis of jadeite jade genesis is reviewed, the geological characteristics of jadeite jade in the world is summarized, the types and characteristics of fluid inclusions are described, the relationship between jadeite jade texture and its genesis is discussed, a new viewpoint——magma genesis of jadeite jade——is put forward, and the p t condition under which jadeite jade crystallized is analyzed. The magma from which jadeite jade crystallized is hydrous jadeitic silica melt which may come from mantle. The crystal condition is p >1.5 GPa, t=650~800℃. This hypothesis of magma genesis put forward before.
