| 中文摘要: |
| 青海省同德县加吾矿区处在东昆仑—西秦岭衔接部位的青海南山冒地槽带。区内地层以隆务河群中三叠统为主,构造主要为北北西向,除曲如沟花岗闪长岩体外,其余以岩脉产出。区内矿体产出受地层、构造、岩浆岩等多种因素控制,矿床成因属中低温热液型金—砷—多金属矿床,成矿时代为印支晚期—燕山期。找矿标志有色调、化探异常、矿物组合、地形、脉岩等。 |
| 英文摘要: |
| The Jiawu mine area, Tongde county, Qinghai, is located in Nanshan geosyncline zone of the jointing part between the Eastern Kunlun and the Western Qinling. In this area, the most important stratum is middle Trassic Longwuhe Group, the most important strike direction of structure is NNW, and all magmatic rock are dyke accept the granodiorite in the Quru channel. The ore bodies are controlled by stratum, structure, magmatic rock and other factors The ore deposit belongs to middle-low temperature hydrothermal gold-arsenic-multiplicity metal type, formed in the late Indo-Chinese o Yanshan Epoch. The ore guide for prospecting includes the hue, geochemical anomaly, mineral association, topography, dyke and others. |
