| 摘 要： | 在梅山铁矿接替资源勘查中,首次发现了金、铜、钼多金属矿体,通过岩石学、流体包裹体及激光等离子质谱(LA-ICP-MS)锆石U-Pb同位素测年等手段初步研究了其成矿地质特征及矿床成因。金、铜、钼多金属矿体主要赋存在铁矿层顶部和外围硅化、黄铁矿化、碳酸盐化的"近矿指示蚀变带"中,属于燕山早期大王山旋回的产物,矿床成因类型为陆相火山-沉积期后热液交代充填型矿床。

| Abstract: | The authors found Au, Cu, Mo polymetallic ore bodies in Meishan Iron Mine in the course of replacement mineral re- sources exploration and studied the geological characteristics and genesis by petrology, fluid inclusion and LA-ICP-MS zircon U-Pb iso- topic dating. Au, Cu, Mo polymetallic ore bodies were occurred in the top of the iron formation and peripheral silicification, pyritiza- tion, carbonate which was so-called ＂near-ore indication the alteration zone＂ which belonged to the product of Dawangshan cycle in early Yanshanian. Genesis type was continental volcano-post-depositional hydrothermal filling deposits. |
