摘　　要：甘肃北山某地区位于甘肃省北山造山带南带,塔里木板块东缘,是连接哈萨克斯坦-塔里木-中朝-西伯利亚板块的纽带,是一个多旋回的复合造山带。本文通过对区域地质背景、典型矿床的综合研究与分析,认为该区具有寻找韧性剪切带型金矿、岩浆期后热液(脉)型钨矿、岩浆岩熔离型铜镍矿的有利条件。综合圈定重点成矿远景区4个;优选找矿靶区9个,其中A类2个,B类3个,C类4个。本次研究为本区下一步开展矿产资源勘查评价和找矿靶区优选提供了科学依据,指明了地质找矿方向。A certain area of Beishan in Gansu Province is located in the southern belt of the Beishan Orogenic belt in Gansu Province,at the eastern edge of the Tarim plate.It is the link connecting the Kazakhstan Tarim China North Korea Siberia plate.It has a long geological evolution process and complex structural and structural combination of the Orogenic belt,and is a multi cycle composite Orogenic belt.Through a comprehensive study and analysis of the regional geological background and typical ore deposits,this article believes that the area has favorable conditions for searching for ductile shear zone type gold deposits,post magmatic hydrothermal(vein)type tungsten deposits,and magmatic rock melting separation type copper nickel deposits.Comprehensively delineate 4 key mineralization prospect areas;Select 9 target areas for ore exploration,including 2 in Class A,3 in Class B,and 4 in Class C.This study provides a scientific basis for the next step of mineral resource exploration and evaluation in this area,as well as the optimization of prospecting target areas,and points out the direction of geological exploration.
