| [摘要]通过对前孙家金矿矿区构造控矿规律研究可知,本区控矿构造型式为成矿前北东向压扭性断裂构造系统中构造透镜体四周的环边式“X冶型断裂,控矿构造具有北北东向、近南北向的优选性,成矿期的构造应力场表现为左旋斜滑运动,主断裂带上的南西向侧伏构造控制了矿体延深。矿区成矿元素组合为Au、Ag、As、Co、Mo、Sn。构造地球化学高值带具有与矿体侧伏方向的一致性。根据控矿构造型式、矿体产出规律、成矿期构造应力场分析和数值模拟以及Au 构造地球化学异常和成矿因子得分等值线图等方面成果综合分析,提出矿区下一步找矿有利地段有三处:4 号脉的南西深部、2 号脉的南西深部和新1 号脉西侧。 |

| Abstract:Based on the investigation of structural ore-controlling regularity in mining area, it is known that the ore-controlling structure type is "X"
ring faults around the tectonic lens in NE compresso-shear fault system. The optimum direction of ore-controlling structure is NNE and near SN. The tectonic stress field of mineralization of sinistral oblique-slip shear, and the deepening of orebody is controlled by the structure of SW lateral trending of main fault. Ore-forming elements composition of mining area is Au, Ag, As, Co, Mo and Sn. Tectonic geochemical high value zone is consistent with orebody's lateral trending regularity. Ore-controlling structure type, ore-body occurence regularity, structural stress field analysis of mineralization period and numerical simulation, tectonic geochemical anomaly of Au, and metallogenic factor scores contour map reveals the favorable prospecting districts: the deep of SW of vein No. 4, the deep of SW of vein No. 2 and the second is the west of new vein No. 1 |
