Preliminary discussion of the the metallogenic conditions of emerald deposit,Southern Xinjiang,China

The emeralds of Xinjiang are good in quality,and the deposit has enormous potential yields of excellent quality emerald.This paper is mainly to analyze the geological characteristics of this deposit, including the regional geological features; mining and geological characteristics of ore body; ore mineralogical characteristics of micro. The formation and distribution of emerald ore bodies found in Xinjiang are controlled by regional stratigraphy, magmatic, tectonic and other factors. Emerald (Beryl) Produced in the carbonaceous limestone, shale, calcite, calcite-quartz veinlets. Veins mostly were shaped by oblique veins, bedding pulse. Based on this study, according to samples collected, carrying on microscopic order of mineral assemblages and the formation of micro-mineralogy, mineralization process will be divided into three periods, namely before mineralization, mineralization period, after forming,obtained in the main ore minerals of the formation of calcite, quartz, albite, beryl, etc.. Through this research, the area emerald (beryl) exploration of important guiding significance.
