摘要
谢家沟金矿是胶东地区新发现的金矿,经研究命名为同韧性剪切带蚀变岩型金矿,焦家金矿则是“破碎蚀变岩型”金矿的命名地;前者是韧性剪切带控矿,后者是脆—韧性断裂控矿;前者研究程度较浅,而后者已为大家所熟知。为了弄清谢家沟金矿的矿床地质特征和成因,本文对两种不同类型的金矿进行了详细的对比研究。
    本文主要从矿床地质、矿床地球化学、稀土元素地球化学、同位素地球化学及流体包裹体地球化学几个方面进行研究。
    矿床地球化学特征研究表明,谢家沟金矿的主成矿因子为F1:Au、Ag、As、Bi、Cu、Pb、Mo、Sb、Co、Ni、Mn,代表了该金矿主成矿期的微量元素组合,其原生晕轴向分带序列表明矿体的规模小而多,多呈叠加状产出;焦家金矿主要针对两种不同类型的蚀变岩矿化进行研究,即Ⅰ号脉绢英岩和Ⅲ号脉钾化花岗岩,研究发现,Ⅰ号脉矿体主成矿因子为Au、Ag、As、Bi、Pb,Ⅲ号脉矿体主成矿因子为Au、Ag、Sb、Hg、Bi、Co、Cu、Pb、Zn。
    稀土元素地球化学研究表明,谢家沟金矿矿石和黑云母花岗岩的形成在物质来源及形成演化机制上具有明显差异;而焦家金矿的矿石、花岗岩以及胶东群地层的稀土配分曲线却近于拟合,说明它们在物质来源上具有同源性,可以判断其成矿物质来源是胶东群重熔的结果。
    同位素研究表明,谢家沟金矿和焦家金矿的成矿时代差别不大,均为100—180Ma,为燕山运动早中期的产物;Pb 同位素研究表明,焦家金矿的成矿物质不是单一来源,以胶东群为主,并有后期岩浆热液叠加成矿;氢氧同位素研究发现,焦家金矿的成矿热液主要为大气降水,并有岩浆水和变质水的加入。
    流体包裹体研究表明,谢家沟金矿为深部中温热液成矿特征,而焦家金矿为中深部中温热液成矿特征,二者的成矿压力分别为2200×105 Pa 和800×105Pa。
    最后,在上述研究基础上探讨了谢家沟金矿和焦家金矿的成矿模式。
Xiejiagou gold deposit is a newly found gold deposit in Jiaodong area, which is named as a syn-ductile sheer zone altered rock-type gold deposit. Jiaojia gold deposit is the locality where the fractured altered rock-type gold deposit is named. The former is controlled by a ductile sheer zone, while the latter is controlled by a brittle-ductile fault. The study degree of the former is lower, while the latter is known very well by people. In order to make clear the geologic feature and the genesis of Xiejiagou gold deposit, the text compares the two gold deposit types in detail.
    The study is carried through from deposit geology, geochemical feature, rare earth element geochemistry, isotope geochemical feature and fluid inclusion geochemical feature.
    The study on the geologic feature shows that the ore-controlled structure of Xiejiagou gold deposit mainly is a ductile sheer zone. Although there are some little faults is Xiejiagou gold deposit, they are formed after mineralization. They destroyed mineralization.
    The study on the geochemical feature shows: the main metallogenic factor of Xiejiagou gold deposit is F1: Au、Ag、As、Bi、Cu、Pb、Mo、Sb、Co、Ni、Mn, which is the microelement assemble of the main Au-metallogenic period. Its axial zoning sequence of the primary halo suggests that the scale of its orebodies is small, which are mainly overlapped. The main metallogenic factor of orebody Ⅰin Jiaojia gold deposit is F1: Au、Ag、As、Bi、Pb; that of orebody Ⅲis F1: Au、Ag、Sb、Hg、Bi、Co、Cu、Pb、Zn.
    The study on rare earth element geochemical featrue shows: there are obvious difference in matter origin and evolvement mechanism between the formation of Xiejiagou gold deposit and the formation of biotite granite. The rare earth element distribution curve of ore, granite and Jiaodong group stratum is nearly fitted in Jiaojia gold deposit, which suggests the matter origin is uniform. We can determine that it is the result of the remelting of Jiaodong group stratum.
    The study on isotope geochemical feature shows: there is no obvious difference in the metallogenic age between Xiejiagou gold deposit and Jiaojia gold deposit, both
