摘要
随着金矿床勘探工作的进行,开采程度逐年降低,金矿勘探出现供不应求的问题,因此对川西北地区金矿成矿地质背景进行调查,分析找矿潜力,为金矿找矿提供理论依据,指导找矿工作顺利进行。从大地构造位置和区域地层分布两方面,对川西北地区地质背景进行归纳与总结;对金矿矿床成因进行探讨,从构造、蚀变、岩浆岩和矿物等方面分析金矿找矿潜力,并进行找矿潜力评价,为该区域后续金矿找矿工作的持续进行奠定科学依据,以促进川西北地区金矿勘探的进一步发展。
With the progress of gold deposit exploration,the mining degree is decreasing year by year,and the gold exploration is in short supply.Therefore,the geological background of gold mineralization in Northwest Sichuan is investigated,and the prospecting potential is analyzed,so as to provide theoretical basis for gold prospecting and guide the prospecting work to proceed smoothly.This paper summarizes the geological background of Northwest Sichuan from two aspects of geotectonic location and regional stratigraphic distribution,discusses the genesis of gold deposits,analyzes the prospecting potential of gold deposits from the aspects of structure,alteration,magmatic rocks and minerals,and evaluates the prospecting potential,so as to lay a scientific basis for the continuous gold prospecting work in this region,so as to promote the gold in Northwest Sichuan Further development of mineral exploration.
