新疆石墨资源特征及成矿规律
Characteristics and Metallogeny Regulation of Graphite Resources in Xinjiang
摘要
Abstract
Graphite is an indispensable strategic resources in the development of high-tech industries.China is rich in graphite resources,but they are mainly distributed in the eastern part of China.In recent years,Xinjiang was found to host a batch of large graphite deposits in the areas,such as Huangyangshan,Kongkere,Dabuxun,and Tuerkuli.With a total of proven graphite reserves more than 100 million tons,Xinjiang has become an important province for graphite production.This is expected to change distribution pattern of China's graphite resources.According to the genesis of the deposits,graphite deposits in Xinjiang can be divided into regional metamorphic graphite deposits,contact metamorphic graphite deposits and magmatic hydrothermal graphite deposits.The regional metamorphic graphite deposits mainly distributed in regional metamorphism strata around old blocks,with its metallogenic epoch mainly focused on the Proterozoic and Early Paleozoic.The contact metamorphic type graphite deposits are mainly distributed in Devonian-Carboniferous clastic rocks in the Paleozoic orogenic belt of eastern Junggar,with the metallogenic epoch extending mainly from the Late Carboniferous to the Early Permian.The Magmatic hydrothermal graphite deposits occur mainly in Hercynian (320～270 Ma) alkali feldspar granite,and its metallogenic epoch consistent to that of magma intrusion.Based on the type of graphite genesis,orecontrolling factors and typical graphite deposits,two graphite mineralization zones and six metallogenic sub-zones have been divided.The study will provide a theoretical basis for graphite survey and ore prospecting in Xinjiang.关键词
