| 摘 要： | 南山钨钼多金属矿是皖南近年来的找矿成果之一。矿体主要赋存于岭脚黑云母花岗闪长岩体北、南部变质接触带内的寒武系杨柳岗组和震旦系兰田组地层内。矿床的形成得益于岭脚岩体的侵入,促使钨、钼等元素大量进入热水溶液,形成含矿流体,同时伴随着北东向断裂的活动,矿液得以运移至由成分复杂的碳酸盐岩矽卡岩化形成的角岩类中富集成矿。南山钨钼矿床是岭脚岩体的侵入作用、热液蚀变作用、围岩条件、热液运移和区域构造活动等因素综合作用的结果,是受一定层位控制的接触变质-中高温热液充填交代型矿床。本文中,笔者通过对南山钨钼矿床地质特征及控矿因素和矿化富集规律的分析,总结了区域上寻找该类矿床的找矿标志,为皖南地区进一步的地质找矿提供实践经验和理论依据。

| Abstract: | The Nanshan W-Mo polymetallic ore deposit in South Anhui achieved great progress in ore prospecting in recent years.The ore body mainly occurs in the southern and northern contact metamorphic zones developed by the Lingjiao biotite granodiorite body intruding into the Yangliugang Formation of Cambrian（∈2y） and Lantian Formation of Sinian.The formation of the Nanshan ore deposit is benefit from incursion movement of the Lingjiao biotite granodiorite rock mass,and the W,Mo elements in it came out into the thermal water to form ore fluid.As the northeast fault movement,the ore fluid is carried into hornfels from skarnization of the carbonate with complicated component to mineralize ore deposit.The Nanshan W-Mo ore deposit is from Lingjiao rock mass incursion,hydrothermal alteration,wall rock alteration,ore fluid migration and regional structure movement,and it is a contact metamorphic-hydrothermal replacement deposit with partial stratigraphic control.Based on the detailed study of the geologic characteristic,ore-control factors and enrichment rules,the prospecting indicators can be summarized to provide practical experience and theory evidence for geological exploration in south Anhui. |
