| 中文摘要: |
| 瓦勒根金矿床位于同德—泽库成矿带东段,区域上与甘肃省境内的夏河—岷县成矿带相接,与枣子沟、寨上、大桥、阳山金矿床具有等距分布的规律,显示出巨大的找矿潜力。文章针对瓦勒根金矿床进行了地质特征及矿床成因分析,研究表明:矿床严格受控于近东西向和北西向层间破碎带、裂隙,发育硅化、褐铁矿化、绢云母化,伴随辉锑矿化发育；中—下三叠统隆务河组第三岩性段(T1-2l3)泥质细碎屑岩可能为区域内金矿床的主要矿源层；矿床与侵位于近东西向断裂破碎带中的石英斑岩(脉)有密切联系,岩体(脉)含量较高的Au介于4.9×10-9～32.6×10-9之间,最高达300×10-9,因此,石英斑岩(脉)可能为矿区的另一矿源层；矿床与枣子沟、寨上、大桥、阳山金矿床具有一致的大地构造环境背景,成矿地质背景条件类似,其成因类似,均属于微细粒浸染型金矿床。 |

| The Walegen gold deposit is located in the eastern section of the Metallogenic belt of Tongde-Zeku, and is connected with the Xiahe-Minxian metallogenic belt in Gansu Province, with Zaozigou, Zhaisahng, Daqiao, Yangshan Gold Deposit has the law of isometric distribution, which shows great potential for prospecting. In this paper, the geological characteristics and Genesis analysis of the Walegen gold deposit are analyzed, and the results show that the deposit is strictly controlled by the Near East-west and northwestward interlayer crushing zone, fracture control, development of silica, browning, Sericite, accompanied by the mineralization and development of antimony; the third lithologic segment (T1-2l3) of the middle and Lower Triassic Longwu Group The muddy fine clastic rock may be the main source layer of the gold deposit in the region, and the deposit is closely related to the quartz porphyry (veins) in the Near East and West fault fracture zone, and the AU content with high rock mass (veins) is generally between 4.9×10-9~32.6×10-9 and up to 300x10-9, so quartz porphyry (veins) May be another source layer in the mining area; The deposit has a consistent tectonic environment background with Zaozigou, Zhaisahng, Daqiao and Yangshan gold deposit, and the metallogenic geological background conditions are similar, the Genesis is similar, all belong to the fine granular leaching type gold deposit, which has great prospecting potential. |
