| 摘 要： | 铜石金矿田位于鲁西中生代富碱次火山杂岩体--铜石岩体周围,该岩体侵入于燕山晚期,主要有闪长玢岩、二长斑岩和隐爆角砾岩组成.岩体与金矿田有密切的成因关系,目前一般认为铜石金矿田金元素来源于泰山群地层,岩体与金矿是衍生关系而非同源关系.但文章通过对铜石金矿田地质特征、流体包裹体成分、氢氧同位素证据、锶、氧和铅同位素比值、碲元素地球化学特征以及国内外成矿地质条件相似地区研究成果分析得出新的观点:铜石金矿田金元素来源于深部碱性玄武岩浆,矿体与岩体是同源而非衍生关系.该新认识对鲁西黄金找矿具有一定参考价值.

| Abstract: | Tongshi gold field is located around Tongshi alkaline igneous sub-volcanic complex in the west Shandong province of China. The early Yanshanian complex mainly consist of dioritic porphyrite, monzonite porphyry and cryptoexpision breccia. Gold mineralization has a close relation with Tongshi rich-kalium sub-volcanic magma activities which provided hydrothermal fluids and heat sources. It was once thought that Taishan group was main gold source bed. However based on the studies on geologic characteristic, fluid inclusion, hydrogen-oxygen stable isotopes, sulfur stable isotopes, ratios of strontium and oxygen as well as lead stable isotopes, tellurium geochemistry, and research results of similar gold deposits both in domestic and international, a new perspective for the genesis of the gold field is proposed that Tongshi gold field is directly derive from the alkaline basalt magma in mantle, in other word , the gold field has direct genetic relation to the Tongshi alkaline complex rocks. This new acknowledge has some consulting meaning for gold exploration in the western Shandong province. |
