| 中文摘要: |
| 小盆地南位于青海祁漫塔格西段,大地构造位置位于祁漫塔格北坡岩浆弧带,成矿地质条件优越。在综合分析该地区地质条件的基础上,对区内的2个1∶1万土壤地球化学综合异常进行了较为系统的查证,初步圈定了10条含金毒砂绢英岩化花岗斑岩脉,确定区内含矿岩性为毒砂绢英岩化花岗斑岩脉,初步建立了地质、地球化学及构造的找矿标志,探讨了矿床的成因为岩浆热液型,分析认为区内具较好的找矿前景。 |
| 英文摘要: |
| The southern of the small basin is located in the western Qimantag. Tectonically, it is located in the magmatic arc on the northern slope of the Qimantag, and have advantage for metallogenic geological conditions. On the basis of comprehensive analysis of geological conditions in this area, two comprehensive geochemical anomalies of 1∶10000 soils in this area have been verified. Ten gold-bearing arsenopyrite sericitized granite porphyry veins have been preliminarily delineated. Moreover, the ore-bearing lithology has been determined to be arsenopyrite sericitized granite porphyry veins. The prospecting criteria of geology, geochemistry and structure have been preliminarily established, and the genesis of the deposit is magma hydrothermal type. This study confirm there have good prospect in this region and also have guiding significance for regional prospecting work. |
