摘　　要：嵩县雷门沟斑岩型钼矿床为一特大型钼矿,控矿斑岩体为燕山晚期侵入的正长花岗斑岩-斑状二长花岗岩。岩体与围岩热液蚀变作用复杂强烈,岩体外侧及顶部发育有隐爆角砾岩带,角砾岩带规模、形态在岩体的不同部位有一定差异,角砾成份复杂。隐爆角砾岩带因孔隙发育,是成矿热液运移、循环的重要部位,也是钼矿化富集的重要场所。本文重点研究了雷门沟斑岩型钼矿隐爆角砾岩带的结构、构造、发育特点及与斑岩体的关系,为深入研究雷门沟钼矿成矿作用提供了新的思路。Leimengou porphyry molybdenum deposit in Songxian county is a very large molybdenum mine,and the controlled porphyry is the normal granite porphyry-porphyry secondary granite invaded in the late Yanshan period.The hydrothermal erosion effect of the rock body and the surrounding rock is complex and strong,and the blasting conglomerate belt is developed on the outside and top of the rock body.The conglomerate belt has different scale and morphology in different parts of the rock body,and the conglomerate composition is complex.It is an important part of hydrothermal transportation and circulation and an important place for molybdenum mineralization enrichment.This paper focuses on the structure,development characteristics and relationship between cryptoexplosive breccia zone and porphyry mass,and provides new ideas for the further study of molybdenum ore.
