四川木里俄堡催金矿体特征及资源量估算

Characteristics and Resource Estimation of the Obouchi Gold Orebody of in Muli County,Sichuan Province

俄堡催金矿床地处四川省木里县境内。金矿层赋存于三叠系上统曲嘎寺组第三段第一亚段, 矿层主要呈透镜状、似层状产出, 延伸较为稳定。矿区范围内共圈定金矿体10个, 通过地质详查工作和资源量估算, 查明该矿床为小型金矿床。矿体似层状、脉状和大透镜状产出, 矿体较连续, 形态较规则, 产状变化简单, 矿体形态较为简单; 其氧化带矿石具有厚度较大, 品位较低, 矿石成分单一, 易选、易开采等特点, 具有一定的综合开发价值。

The Obouchi gold deposit located in Muli County, Sichuan Province within the first sub-member of the third member of Qujiasi Formation in the Upper Triassic Series. The deposits are predominantly lens-like and stratified with a relatively stable extension. A detailed geological survey and resource estimation revealed 10 small gold deposit bodies within the mining area. These ore bodies occur in vein, stratiform. and large lens shapes with regularity and continuity. The oxidation zone ores exhibit characteristics such as large thicknesses, low grades, single mineral component but simple extraction potential with development value.
