摘　　要：四川省西部是该省岩金矿床重要且较集中的产地,2011年实施找矿突破战略行动以来,四川省在岩金找矿中也有较多新发现,但总体上金矿勘查开发进展缓慢,地质工作程度较低。本文从各矿床成因类型中选取层控-热液型东北寨金矿床、构造-热液型张家坪子金矿床、海相火山岩型梭罗沟金矿床、斑岩(玢岩)型金木达金矿床、岩浆热液型黄金坪金矿床及接触交代(矽卡岩)型阿西金矿床作为研究对象,在重点介绍其矿床地质特征及勘查程度的基础上,总结其成矿地质共性特征,并探讨四川省西部各典型岩金矿床成矿规律,以期为该地区的岩金矿找矿工作提供一定参考,助力同类型金矿资源勘查与评价工作。Western Sichuan Province is an important and relatively concentrated region of rock-gold deposits.Since the strategic action of prospecting breakthrough in 2011,there have been many new discoveries in rock-gold prospecting in Sichuan Province,but the progress in gold deposit exploration was slow and little geological work degree is carried out.In this paper,layer-controlled hydrothermal type Dongbeizhai gold deposit,structural hydrothermal type Zhangjiapingzi gold deposit,marine volcanic type Suoluogou gold deposit,porphyry(lamprophyre)type Jinmuda gold deposit,magmatic hydrothermal type Huangjinping gold deposit,and contact metasomatic(skarn)type Axi gold deposit are selected as the research objects.Based on the introduction of geological characteristics of these deposits and exploration degree,the general metallogenic geological characteristics are summarized,and the metallogenic regularity of each typical rock-gold deposit in western Sichuan Province is discussed,aiming to provide reference for the prospecting of rock-gold deposits in this area,and support the exploration and evaluation of similar gold deposit.
