| 中文摘要: |
| 五龙沟金矿田位于柴达木陆块南缘的东昆仑中带地区,至今已发现10余条金矿化带,其中Au含量一般为1×10－6～n×10－6,最高可达171×10－6。金矿化带呈近平行斜列展布,走向延长稳定,最长延伸超过10 km。矿床围岩蚀变十分强烈,以硅化、绢云母化、黄铁矿化、毒砂矿化与金矿化关系密切。金矿矿石类型主要为构造蚀变岩型,次为石英脉型两种,金矿成矿主要受北西—北西西向剪切带及脆性复合断裂构造和印支期闪长玢岩为主的浅成—超浅成中性岩两种因素控制,金矿主体表现为受剪切带控制的中低温热液构造蚀变岩型矿床。 |
| 英文摘要: |
| Wulonggou gold field is located in the East Kunlun, southern margin of The Qaidam land block, So far, more than 10 gold mineralized belts are found, the gold content in general is 1×10-6～number of ×10-6, up to 171×10-6,gold zone was nearly parallel to the diagonal spread, to extend the stable, the longest extension of more than 10km. Deposits in wall-rock alteration is very strong, closely related to silicification, sericitization, pyritization, arsenopyrite mineralization and gold mineralization. Gold ore types altered rock type, for both quartz vein type gold mineralization by the NW-NWW trending shear zones and brittle composite fracture structure and Indosinian diorite porphyrite-based shallow - super shallow neutral rock two factors control the gold main performance by the shear zone in the low-temperature hydrothermal altered rock gold. |
