沙坪沟斑岩型钼矿含矿岩体及其蚀变特征

Shapinggou porphyry molybdenum ore-bearing intrusion and its alteration features

金寨县沙坪沟钼矿尚处在详查阶段。该矿床规模大,品位高,矿化高度集中,具有矿化时间长,蚀变强度高,成矿期次多等特点。本文从矿区岩浆岩、含矿岩体、成矿岩体及其蚀变特征入手,来探讨该矿床在成矿作用方面的的上述特点。

The Shapinggou molybdenum ore deposit in Jinzhai County is still in the phase of detailed exploration.It is large in size,high in grade,highly centralized in mineralization,the scale of which is unrivaled by others of its kind,especially its big ＂momentum＂.The deposit has experienced a long period of mineralization,shows intense alteration and multiple phases in ore formation.This paper discussed the above characteristics of the deposit in mineralization in view of igneous rocks,ore-bearing intrusion,mineralized intrusion and its alteration features in the area.
