The primary ore body of jadeite jade in the lenticular form intruded into the serpentinous ultrabasic rock. The formation of the ore body can be divided into four geological processes in order of magmatism (rock forming)→metamorphic recrystallization→tectonic stress→jade forming. Three colors of occurrence in the ore body are respectively light purple, black and green. It is considered that the violet color of jadeite jade is the earliest primary color formed by magmatism, the black color results from the torendrikite formed by metamorphic recrystallization of trapped massive in the ore body, and the green color of jadeite jade is the latest color caused by the formation of jade. Chrome in the green color of jadeite jade is derived from the trapped massive in the ore body and is related to tectonic stress.
