【摘要】 熊耳山地区是豫西重要的金矿化集中区。通过对该区花山花岗岩的化学组成、微量元素、稀土元素、稳定同位素特征及与金矿化关系的研究,得出如下主要研究成果:(1)在R型聚类分析谱系图上表明岩体中Au、Ag、Pb、Cu、Ba元素与金矿床微量元素相关性趋于一致;(2)在稀土元素配分模式图上表现出花岗岩和蚀变岩具有相似的右倾配分曲线的特征;(3)在流体包裹体的w(Na+)-w(K+)-w(Ca2++Mg2+)成分三角图上表明金成矿流体和岩浆热液具亲缘关系;(4)岩体线性构造控制了花山地区构造蚀变岩型和爆破角砾岩型金矿床的时空分布;(5)金矿床的成矿时代为燕山期,花山花岗岩的成岩时间集中于81~159 Ma;(6)S、H、O、Pb同位素组成表明成矿物质和成矿流体来自岩浆热液。更多还原

【Abstract】 Xiongershan is an important concentration area of gold mineralization in western Henan.By studying geochemical compositions,trace elements,REE,stable isotopes of Huashan granite and its relations with gold deposits,the following research achievements have been obtained:（1）R-clustering spectrum diagram shows that correlations of trace elements such as Au,Ag,Pb,Cu,Ba of granite and gold deposits tend to continuity;（2）REE distribution pattern shows similar right-dipping forms of granite and the altered rocks;（3）Na⁺-K⁺(-Ca²⁺)+Mg²⁺composition of fluid inclusions diagram shows intimate relationship between gold metallogenic fluids and magmatic hydrothermal fluids;（4）Space-time distribution of structure-controlled alteration rock type gold deposits and explosion-breccia type gold deposits in Huashan area is controlled by linear structures of Huashan granite;（5）Metallogenic epoch of the gold deposits is Yanshanian period,and the rock-forming age of Huashan granite occured in 81-159 Ma;（6）S,H,O and Pb isotopes show that the ore-forming fluid and（metallogenic） material come from magmatic hydrothermal fluids.更多还原
