The primary jadeite jade orebody in the lenticular form intruded into the serpentinous ultrabasic rocks. Trapped massive bodies with composition of country rocks are distributed in the jadeite jade orebody. The order of crystallization in the orebody is coarse-prismatic jadeite with broom-like texture→fine-prismatic jadeite with interlocking texture→veins of macro-prismatic jadeite with flowage structure and granulous analcite→veins of analcite→veins of albite and quartz. The green jadeite jade, 0.06～0.08 mm in length and 0.01～0.015 mm in width, consists mainly of macro-prismatic jadeite with flowage structure. The orebody consists mainly of fine-prismatic jadeite with interlocking texture. It is held that the jadeite jade orebody was formed bythe evolution of ultrabasic magma during crystallization.
