青海省兴海县鄂拉山口东多金属矿区成矿地质条件及找矿远景浅析

Ore一forming Geological Conditions of Elashankoudong Multi-metal Mine Area and Prospects Analysis for Exploration in Xinghai County,Qinghai Province

鄂拉山口东多金属矿区发现于20世纪90年代,矿区位于柴达木地块东南缘--鄂拉山火山-岩浆弧弧前增生楔西南部之颚拉山造山带南部,处于东西向构造带、北北西构造带和北东向构造带的交汇处。是青海省重要的多金属成矿带--鄂拉山多金属成矿带。本文通过对鄂拉山口东多金属矿区的成矿地质条件的初步分析,来阐述该区较好的找矿远景。

Elashankoudong multi-metal mine area was discovered in 1990s, it is in the southeastern margin of Qaidam massif-the south of Elashan orogenic belt of the southwestern of Elashan volcano magmatic arc forearc accretionary wedge, just on the intersection of east-west tectonic belt, the NNW trending tec-tonic belt and North East tectonic belt. and it is an important polymetallic ore belt in Qinghai Province-Elashankou metallogenic belt. This paper expounds prospecting potential of Elashankoudong multi-metal mine area on the basis of the study of ore-forming geological conditions.
