摘要:
东峰顶金矿区呈脉状赋存于断裂破碎带中,矿石类型为硫化物石英重晶石脉型,矿体围岩蚀 变强烈,根据矿床地质、地球化学特征,结合矿体矿物共生组合、铅和硫同位素组成及成矿年龄、包裹体 成分及特征以及原生金的成色等研究,认为金矿床矿源为重熔岩浆岩。成矿溶液主要来自岩浆水和大 气降水的混合溶液,成矿温度140℃～400℃,成矿深度约1.5km。矿床成因类型属中温、中深条件下形 成的岩浆热液充填型金矿床。
Abstract:
Taershan-Erfengshan district , located at southern Shanxi Province , is an upwarping subunit in the Linfen basin, and bas an area of about 900 km2.The subunit was active in alkaline and subalkline magmatism during Mesozoic Yanshan period , and has a great potential for looking for gold deposits because the gold mineralization is widespread .The study on the Dongfengding gold deposit is essential in enlarging the size and perspective of the gold deposit.The veins of the Dongfengding gold deposit occur in faults, and the mineralization is of goldbearing quarts-sulfide-barite vein with strong alteration in wall-rocks.It is proposed in this paper that the mineralization resulted from anatexis magma according to the reatures of ore geology , geochemistry , mineral assemblage , lead and sulfur isotopes, mineralization age , compositions of inclusions in minerals and purity of gold.The mineralized solution was mixture of magmatic water and meteoric water , and the ore veins formed under the condition of 140～ 400 ℃ temperature and about 1.5 km depth.The manner of mineralization is injection type of gold-bearing hydrothermal solution at moderate temperature and moderate depht .
