摘要
甘肃省礼(县)岷(县)金矿带地处西秦岭复杂构造带东段,是除西(西和县)成(县)铅锌矿带以外该地区最为重要的勘采活动区。根据已有资料不完全统计,沿金矿带已发现金矿床(点)多达数十余处。本区金矿成矿与地层、构造、岩浆岩关系密切,金矿带总体呈北西向展布,具带状延伸,金矿化有分段集中、成群产出的特点。从礼岷金矿带东段金地质成矿背景、成矿区带划分入手,分析金矿产出规律和金矿成矿的控制因素,提出礼岷金矿带东段金矿找矿方向,对该区金矿勘查工作部署具有一定的参考意义。
The Lixian-Minxian gold deposit belt in Gansu Province is located in east sector of the complicated tectonic belt in the western Qinling Mount. It is the most important exploration-exploitation area except the Xihe-Chengxian lead-zinc de- posit belt. According to current information of incomplete summary, tens of gold deposit sites along the gold deposit belt were found. The gold mineralization in this area is closely related to the strata, tectonics and magmatic rocks. The gold belt spreads in northwest stride with band stretching, featuring sectored accumulation and clustered output for the mineralization. From gold mineralization settings and the mineralization belt delineationfor the east sector of the LiXian-MinXian gold de- posit belt, the output pattern and controlling factors of the mineralization belt was analyzed , and prospecting direction for the LiXian-MinXian gold deposit belt was proposed, providing reference for the exploration and survey work in this area.
