新疆加曼特金矿与阿希金矿的成矿条件及矿物学特征对比研究

Comparative study on the minerogenetic conditions and mineralogical characteristics of Jiamante and Axi gold deposit

阿希金矿与加曼特金矿位于西天山北段的近东西向晚古生代吐拉苏-也列莫顿成矿带。本文着重对两矿成矿条件、矿物学特征、成矿期次进行了对比研究,发现其有一些相同点与差异性,初步认为:加曼特金矿可能属中低温热液过渡型金矿;两矿在成矿温压、金赋存态、成矿流体、成矿期次等方面尽管存在一定差异,但在成因类型上有一定的相似性。

Axi and Jiamante gold deposit are located in near EW Late Paleozoic Tulasu-Yeliemodun metallogenetic zone in the north of the Western Tianshan.In this paper,the minerogenetic conditions,the Mineralogical Characteristics,and the Metallogenic Episodes of the Axi gold deposit are mainly compared with those of the Jiamante gold deposit.Besides,the similarities and differences are found,and some preliminary conclusions are drawed：Jiamante gold deposit may belongs to mesothermal-epithermal veinlike type gold deposit;Axi and Jiamante gold deposit have the external similarity and internal consistency;Though both of them are significantly different in metallogenic temperature and pressure,occurrences of gold,ore-forming fluid,Metallogenic Episodes and so on,they have some certain similarities in the genetic types.
