安徽大别山石英质玉矿矿床地质特征及开发利用前景分析——以霍山县白莲岩地区石英质玉矿为例

GEOLOGICAL CHARACTERISTICS AND PROSPECT OF DEVELOPMENT AND UTILIZATION OF QUARTZOSE JADE DEPOSITS IN THE DABIE MOUNTAIN,ANHUI PROVINCE——AN EXAMPLE FROM THE BAILIANYAN AREA,HUOSHAN COUNTY

大别山地区石英质玉简称“大别山玉”,主要分布于北大别变质杂岩带核部。地层为古元古代—新太古代大别岩群,新元古代中酸性侵入岩、燕山期花岗岩分布广泛,断裂构造极为发育。霍山县白莲岩地区石英质玉矿矿体呈脉状、透镜状伴随硅化构造破碎带产出,玉石颜色丰富,质地细腻,具有一定的经济价值和开发利用前景。

The quartzose jade in the Dabie Mountain area is referred to as the"Dabieshan jade",which is mainly distributed in the core of the northern Dabie metamorphic complex belt,where the strata are Paleoproterozoic-Neoarchean Dabie Group,the Neoproterozoic intermediate-acid intrusive rocks and Yanshanian granites are widely spread,and the fault structures are highly developed.The quartzose jade body is veined and lenticular within silicified tectonic fracture zone in the Bailianyan area,Huoshan County,with the jade being rich in color and fine in texture.The deposit has certain economic value and potential for development and utilization.
