云南黄草地大火房箐铅锌矿地质特征与找矿标志研究

Geological Characteristics and Prospecting Indicators of the Dahuofangyu Lead-Zinc Deposit in the Yellow Grassland of Yunnan

矿区位于滇中盆地与哀牢山造山带东侧红河大断裂北段元江断裂毗邻部位。出露三叠系上统云南驿组,总体构造线呈NW-SE向展布,以断裂、褶皱构造为主。矿体严格受地层岩性、构造的双重控制。矿床成因类型属地下水中-低温热液矿床,地层、构造找矿标志明显。

The mining area is located adjacent to the Yuanjiang fault in the northern section of the Honghe fault in the eastern Yunnan and the Ailaoshan orogenic belt. The Upper Triassic Upper Yunnan-Yunnan Formation was formed, and the overall tectonic line was distributed in the NW-SE direction, with faults and folds being the main structure. The ore body is strictly controlled by the lithology and structure of the stratum. The genetic type of the deposit belongs to the medium-low temperature hydrothermal deposit of groundwater, and the formation and structure of the ore deposit are obvious.
