青海拉陵高里北地区铜多金属矿找矿前景分析

The copper polymetallic ore prospecting potential analysis of the Lalinggaolibei of in Qinghai Province

拉陵高里北地区处于伯喀里克—香日德印支期金、铅、锌、铁、石墨成矿带和祁漫塔格—都兰华力西期铁、铅、锌、钴成矿带中,到目前已发现各类矿床(点)31处。成矿类型有矽卡岩型、斑岩型、岩浆熔离型、热液型及喷流沉积型。其中以矽卡岩型(接触交代型)为主,矿种主要为铁,次为铜、铅、锌。本文通过对区域地质背景、成矿构造环境、成矿地质特征及矿化分布规律的综合研究与分析,认为该区具有寻找矽卡岩型铜多金属矿床的有利条件,为本区下一步开展矿产资源勘查提供了科学依据,指明了找矿方向。

The Lalinggaolibei is located in the Bokalike-Xiangride Indosinian gold,lead,zinc,iron,graphite andQimantage-Dulan Variscan iron,lead,zinc,cobalt metallogenic belt,which has been found thirty-one deposits(point).Metallogenetic types are skarn,porphyry,magmatic segregation type,hydrothermal and sedimentary.Skarn(contact metasomatic type)type is the main type.Main minerals are iron,secondly copper,lead and zinc.Based on theresearch and analysis of regional geological setting,metallogenic tectonic setting,mineralization geological characteristicsand mineralization distribution of comprehensive,the area has favorable conditions of looking for the skarn type copperpolymetallic deposit,which offer a scientific basis for mineral exploration and gold prospecting guidance.
