摘要
青海省都兰县沟里地区金矿的勘查开发已成为青海省东昆仑成矿带东段的重大找矿成果。沟里整装勘查区处在东昆仑成矿带东段,经历了新元古带—早古生代洋陆转化阶段、晚古生代洋陆转化阶段、晚二叠世—中三叠世洋陆转化阶段及其后期复杂的陆内造山过程,区域强烈的构造—岩浆活动为金多金属矿的形成提供了极为有利的条件。通过对沟里地区金矿床的综合分析,确定成矿时代,查明控矿因素,指导后续资源勘查。
The exploration and development of gold mine in Gouli region of Dulan County has become the major prospecting achievement in eastern section of east Kunlun metallogenic belt in Qinghai Province. Guoluo Longwa Gold Mine,including Asha Gold Mine,Walega gold mine,Annage gold mine and polymetallic deposit,are found in this region. It has made Gouli region to Qinghai provincial-level integrated exploration in a national exploration region.Gouli Consolidated exploration region is located in the east part of East Kunlun metallogenic belt. It experienced the Neoproterozoic Paleozoic continental transformation stage,including Late Paleozoic continental transformation stage,Late Permian-Middle Triassic oceanic transformation stage and late complex intracontinental orogenic processes. The strong tectonic-magmatic activity provides the favorable conditions for formation of gold polymetallic ore deposit. Through the comprehensive analysis of the typical gold deposits in Gouli region,we have confirmed the metallogenic age. We also identified the ore-controlling factors to summarize the metallogenic regularity for the follow-up of resource exploration.
