| 摘 要： | 果洛龙洼金矿位于青海省都兰县香日德镇，矿区面积约10km^2。矿区内的金矿体分布于下石炭统中，区内发育的F1、F2、F3三条近东西向断裂为主要断裂，规模大、延伸远，并控制着金矿体的分布。区内的金矿床为构造-岩浆-断裂叠加改造的韧性剪切带型金矿床。根据矿床地质特征，总结出本区内金矿的找矿标志是：岩性标志，构造蚀变带标志，硫化矿物标志，特殊构造部位标志， 蜂窝状构造标志，特征矿物-构造标志，化探异常标志。 |
| 关 键 词： | 金矿 地质特征 矿床成因 找矿标志 |

| Abstract: | The Guoluolongwa gold mineralization covers an area of 10 km2 in Xiangride town, Dulan county, Qinghai provinee. The gold ore occured in the lower Carboniferous, three east-west trend faults, F1, F2, F3, were identified as main faults in the area. The three faults are of large-scale and long-extended, by which the gold ore distribution is controlled. The gold ore in the area occurs in a ductile shear zone with a type of gold deposit folded and reformed again by structures-magma-faults. Some exploration indicators of the gold ore are summed up according to the geological characteristics of the gold ore in the area： lithological Criteria, structural etch zone criteria, sulfide mineral criteria, special structural position criteria, honeycomb structure criteria, characteristic mineral-struct ure criteria, geochemical exploration anomaly indicator. |
