卢氏西虎岭黄铁矿床围岩蚀变特征及其找矿意义

FEATURES OF WALLROCK ALTERATION ZONE OF PYRITE DEPOSIT IN XIHULING OF LUSHI

文章通过对西虎岭黄铁矿床围岩蚀变的研究认为，围岩蚀变大致可分为６种基本蚀变类型，５个蚀变阶段，３个蚀变带。各蚀变带以矿体为中心对称分布，各带之间呈渐变过渡关系。同时认为矿床成因类型属中低温热液充填型，并指出围岩蚀变的找矿意义。

Based on the studies of wallrock alteration of Xihuling pyrite deposit in this paper, the wallrock alteration have roughly been divided into six basical alteration types and five alteration epoch-stages and three alteration belts. Each alteration zone distributed symmetrically taking orebody for the zonal centre, and to have the relations of gradual change and transition between the zone. At the same time auther considered that the genetic type of mineral deposit belonged to the mesothermal-epithermal filling type. At last, the author points out the significanace of the wallrock alteration for the prospecting.
