Geological and geochemical characteristics of Yemaquan gold deposit in Qinghexian county,Xinjiang Autonomous Region

野马泉金矿床位于准噶尔微板块东段,东准噶尔晚古生代陆缘盆地的南部,喀斯开尔索克坎大断裂西侧,哈萨坟复背斜轴部;矿体呈脉状主要赋存于蚀变闪长玢岩脉中及其内、外接触带。蚀变闪长玢岩脉的围岩为志留系库布苏群下亚群粉砂质板岩、千枚岩化粉砂岩;矿床成因类型为次火山热液-变质热液叠加型。

Yemaquan gold deposit is located at axis of Hasafen anticlinorium in the west side of the big Kasikaiersuokekan fault belt in south part of Late Palaeozoic continent marginal basin in the east Zubger area of the micro- Zubger plate. Ore bodies occur in the altered diorite dykes or at their inner and outer contact zones. The altered diorite dykes are enclosed in argillaceous slate and phyllitized siltstone of the Lower Silurian Kubusu group. Genetically, the gold deposit is a sub-volcanic-metamorphic hydrothermal deposit.
