摘　　要：嵩县雷门沟钼矿分布于重要的东秦岭钼成矿带上,控矿斑岩体岩性主要为正长花岗斑岩-斑状二长花岗岩。与成矿有关的热液蚀变作用极为强烈,蚀变矿物种类复杂,充分反映了斑岩型矿床的热液蚀变特征。本文重点研究了雷门沟斑岩型钼矿床的主要蚀变类型,同时揭示了不同的蚀变矿物或蚀变矿物组合的生成先后顺序及与金属矿物矿化的关系,为进一步研究雷门沟钼矿成矿作用提供了新的思路。Leimengou molybdenum deposit is distributed in the important East Qinling molybdenum metallogenic belt.The ore-controlling porphyry is mainly syenite porphyry-porphyry monzonite granite.The hydrothermal alteration related to mineralization is very strong and the alteration minerals are complex,which fully reflects the hydrothermal alteration characteristics of porphyry deposits.This paper focuses on the main alteration types of Leimengou porphyry molybdenum deposit,and reveals the formation sequence of different altered minerals or altered mineral assemblages and their relationship with metal mineralization.It provides a new idea for the further study of the mineralization of Leimengou molybdenum deposit.
