| 摘 要： | 西峡县南沟矿区锑-金矿床位于华北克拉通南缘华熊地块和秦岭造山带的拼合部位二郎坪地体东段。秦岭造山带呈EW向横贯中国大陆中部,是华北板块与扬子板块俯冲碰撞而成的复合型大型造山带。从区域金属矿床(点)空间分布特征看,南沟锑-金矿区及外围分布有一系列呈NW向展布的金、钼、锑矿化带(点)。矿区岩浆岩活动频繁,主要的侵入体为加里东期花岗岩、斜长花岗岩和花岗斑岩,其中花岗岩与成矿关系密切。本文从地层-构造-岩浆岩各因素对成矿的控制作用入手,对南沟锑-金矿成矿物质来源及矿床成因进行研究。

Geological characteristics and genesis of Nangou Sb-Au deposit in Xixia of Henan |

| Abstract: | Nangou Sb-Au deposit in Xixia County of Henan is located in the east section of Erlangping terrane which is at the juncture of Huaxiong land mass and Qinling orogenic belt on the south margin of North China Craton.Qinling orogenic belt,as a large complex orogenic belt caused by subduction and collision of North China plate and Yangtze plate,traverses the central part of mainland China along the east-west direction. From the perspective of regional distribution characteristics of metallic mineral deposits (occurrences),a se-ries of gold,molybdenum,antimony mineralized belts (spots)are distributed along the north-west direction inside Nangou Sb-Au mining area and its peripheral area.Magmatic activities are frequent in the area,and the major intrusive bodies include Caledonian granite,plagiogranite and granite porphyry.Among them, granite is closely associated with mineralization.Starting with the control effect of strata,structure and mag-matic rocks on mineralization,this paper analyzed the ore-forming material source and the genesis of Nangou Sb-Au deposit. |
