河南省钼矿床的分布规律及其控矿地质因素探讨

Distribution regularity of molybdenum deposits in Henan and its geological ore controlling factors

通过对河南省钼矿床的分布规律和控矿地质因素的分析,总结出如下认识:(1)河南省钼矿床属东秦岭—大别山钼成矿带的一部分;(2)在地槽活动带的边缘区的构造-岩浆岩带是钼矿床产出的有利场所;(3)成矿母岩是主要控矿因素,同时也是最重要的找矿标志;(4)区域上巨大的燕山期花岗岩基是成钼小岩体的母岩,而成钼小岩体又是钼矿床的成矿母岩,三者在空间分布上具有高度的一致性。

Following understandings have been summarized through analysis on distribution regularities and geological ore controlling factors of molybdenum deposits in Henan （1）Molybdenum deposits in Henan belong to part of east Qinling-Dabeishan molybdenum ore belt, （2） Structure-magmatite belt at the margin of geosyncline movement zone is a favorable location for molybdenum mineralization, （3） Host rock is the major ore controlling factor and also the most important exploration indicator, （4） Big Yanshanian granite basement in the region is parent rock for small molybdenum forming rock bodies while the small molybdenum forming rock bodies is the host rock for molybdenum deposit. There is a great consistency in special distribution of the three.
