| 摘 要： | 石墨是高新技术产业发展中不可或缺的重要战略资源。我国石墨资源虽然储量丰富,但主要集中分布于东部地区。近年来,新疆新发现黄羊山、孔可热、达布逊、吐尔库里等一批大型石墨矿床,查明资源量超过1亿吨,使新疆一跃成为我国石墨大省,有望改变我国石墨资源分布格局。根据矿床成因特征,新疆石墨矿床可以划分为以下3种类型:(1)区域变质型,主要分布于古老地块周缘元古代深变质岩系中,成矿时代集中于新元古代和早古生代;(2)接触变质型,主要分布于东准噶尔古生代造山带中,含矿岩系为泥盆-石炭纪碎屑岩,成矿时代主要为晚石炭世-早二叠世;(3)岩浆热液型,赋矿围岩为海西期(320~270Ma)碱长花岗岩,成矿时代与岩浆侵入时代一致。根据石墨矿床成因类型、控矿因素及典型矿床特征,将新疆石墨成矿区划分为2个成矿区带,6个成矿亚带,为今后新疆石墨找矿提供理论依据。

| 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, ore controlling 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. |
