摘　　要：祁雨沟金矿田是熊耳山地区7个大型金矿之一,成矿类型主要为隐爆角砾岩型,次为斑岩型和构造蚀变岩型。现有矿床赋存深度一般在500 m以内,最深只有700 m左右,深部找矿工作进展缓慢。本文通过研究祁雨沟隐爆角砾岩型金矿和雷门沟斑岩型钼矿分布规律、形成机制,总结了前人对金、钼成矿流体的研究成果,取得了如下结论与认识:斑岩型钼矿、角砾岩型金矿和脉型金矿为统一的构造、岩浆、流体成矿系统;金钼成矿流体源自岩浆,钼矿成矿物质主要来自下地壳,混有少量地幔成分,金矿成矿物质为壳幔混合;建立了深部钼矿立体成矿模型,从上至下第Ⅰ成矿区为现有勘探工程控制的Au、Mo矿床,第Ⅱ成矿区为根据成矿规律推定的斑岩型、角砾岩型Mo、Au矿床,第Ⅲ成矿区为根据成矿规律推定的斑岩型Mo(Au)矿床,以斑岩型钼矿为主。根据研究成果,预测了深部斑岩型钼矿找矿潜力,供深部找钼矿工作参考。Qiyugou gold deposit is one of the seven large gold deposits in Xiong′er Mountain area,with the main mineralization type being cryptoexplosive breccia,followed by porphyry and tectonic altered rock types.The depth of existing mineral deposits is generally within 500 m,with the deepest being only about 700 m,and the progress of deep exploration work is slow.In order to explore the occurrence of deep mineral resources,this article studies the distribution patterns and formation mechanisms of Qiyugou hidden explosive breccia type gold deposit and Leimengou porphyry type molybdenum deposit,summarizes the research results of previous studies on gold and molybdenum ore-forming fluids,and obtains the following conclusions and understandings:Porphyry type molybdenum deposits,breccia type gold deposits,and vein type gold deposits are a unified tectonic,magmatic,and fluid mineralization system;the ore-forming fluid of gold and molybdenum comes from magma,and the ore-forming material of molybdenum mainly comes from the lower crust,mixed with a small amount of mantle components,gold mineralization is a mixture of crust mantle minerals;a three-dimensional mineralization model for deep molybdenum deposits has been established,with the first mineralization area from top to bottom being the Au and Mo deposits controlled by existing exploration projects,the second mineralization area is inferred to be porphyry and breccia type Mo and Au deposits based on mineralization laws;The third space mineralization area is a porphyry type Mo(Au)deposit inferred based on mineralization laws,mainly consisting of porphyry type molybdenum deposits.Based on research results,the prospecting potential of deep porphyry molybdenum deposits has been predicted,providing reference for deep molybdenum exploration work.
