文章对大湖塘矿集区燕山期岩浆岩从岩体的空间分布、岩石的地球化学特征等方面进行了分析研究,探讨了岩浆岩的成因及其与成矿的关系。结果表明,该矿集区燕山期岩浆岩是一个半隐伏―隐伏的多次侵入的岩株状杂岩体,均属强过铝质的 S 型花岗岩,为岩浆成因,深熔浅成,形成于同碰撞构造环境。各期次岩体 W、Sn、Mo、Bi、Cu、Zn 等成矿元素含量高,矿床、矿体及矿床金属分带均围绕岩体展布,是成矿的母岩。成岩与成矿是先行后续的关系,成矿主要发生在燕山早期。
文章對大湖塘礦集區燕山期巖漿巖從巖體的空間分佈、巖石的地毬化學特徵等方麵進行瞭分析研究,探討瞭巖漿巖的成因及其與成礦的關繫。結果錶明,該礦集區燕山期巖漿巖是一箇半隱伏―隱伏的多次侵入的巖株狀雜巖體,均屬彊過鋁質的 S 型花崗巖,為巖漿成因,深鎔淺成,形成于同踫撞構造環境。各期次巖體 W、Sn、Mo、Bi、Cu、Zn 等成礦元素含量高,礦床、礦體及礦床金屬分帶均圍繞巖體展佈,是成礦的母巖。成巖與成礦是先行後續的關繫,成礦主要髮生在燕山早期。

The distribution and geochemical characteristics of Yanshanian magmatic rocks in Dahutang ore-concentrated area are analyzed in this paper and the genesis of magmatic rocks and its relationship with min-eralization are discussed.The results indicate that Yanshanian magmatic rocks in this ore-concentrated area are a hemi-concealed to concealed stock-like complex body with s of intrusive ages.The rocks also show strongly peraluminous affinity and are classified into S-type granite.The area is magmatogenic,anatectic and supergene,and it is formed in the syn-collisional structural setting.Metallogenetic elements such as W,Sn, Mo,Bi,Cu and Zn are relatively high in rock bodies of each period,and deposit,ore-body and metalzoning of the deposit are distributed around rock body which is the ore-forming mother rock.The diagenetic process happened before the mineralization process.The main mineralization process occurred in Early Yanshanian stage.
