| 摘 要： | 幸福村金矿床位于华北陆块北缘西段，白云鄂博-商都成矿带上，金矿体主要赋存于尔力格图倒转向斜南翼白云鄂博群比鲁特组千枚岩中。从地层、构造及岩浆活动等方面对矿区的控矿因素进行分析，认为金矿体是在地层、构造和岩浆活动“三位一体”的作用下形成的；区内白云鄂博群千枚岩中Au元素含量较高，是金矿形成的初始矿源层；成矿过程中，构造起主导作用，岩浆活动提供了热、液源及动力；结合矿区地质特征和典型矿床对比分析，认为本区属于以浅变质岩为容矿围岩的中-低温热液金矿床。通过成矿作用分析，初步建立了该区的理想成矿模型，指出下一步找矿工作应加大在北倾方向上的工程投入，尤其靠近核部是矿物富集成矿的有利部位。

| Abstract: | Xingfucun gold deposit,located in the Bayunerbo to Shangdu metallogenic belt at the western section of north margin of North China platform,and the gold orebodie mainly exist in the Bayunerbo group Bilute fabric phyllite,in southern limb of the Erligetu overturned syncline.Through study on ore controlling factor from stratigraphic formation,tectonic movement and magmatic activity etc.,we think that the gold ore-body is formed under the integrated function of strata,fractures and magmatic rocks,namely stratum is ore bearing layers.while structure played ore conducting function and the magmatic activity provided heat source and possible ore liquid or dynamic force.Combining with the analysis of deposit geological features,comparing regional different gold deposits,the genesis of Xingfucun gold deposit is attributed to the meso-epithermal type of gold deposits hosted by low-grade metamorphic rock.We initially establish the ideal mineralization model of the area based on the analysis of the mineralization,and we suggest that further prospecting work should focus on the area of north-dipping direction,especially area near the core where is the favorite part of mineral enrichment and mineralization. |
