| 摘 要： | 通过对板－沙地区构造沉积演化，岩相古地理，变质作用构造变形和矿床特征的地质地球化学综合研究，表明马鞍桥矿床属于变持细碎屑岩型层控金矿床。矿床的形成可划分为沉积，变南，构造叠加和热液改造三个阶段。

| Abstract: | Integration of geochemical study on tectonic-sedi-mentary evolution, lithofacies and paleogeography, metamorphism structural deformation and features of deposit in Ban-Sha area suggests that Maan Qiao An deposit is a stratabound gold deposit of metamorphosed fine-elastic rocktype. The formation of this ore-deposit might be divided into three stages: sedimentary stage,metamorphic stage and structural superposition and hydrothermal transformation stage. |
