| 中文摘要: |
| 地质勘查工作在湾子矿区发现了中二叠统茅口组灰岩，表明本区存在晚古生代孤立台地，矿区位于区域性胡家堡断裂北东侧，具备桂西地区典型的“台地+断裂”联合控矿条件。矿区为一宽缓的背斜构造，矿体产于沉积不整合面之上的下三叠统地层中，受断裂破碎带控制，具有典型的微细粒型金矿特征。通过引入“二层楼”矿床模式，结合本矿区成矿条件和矿化信息分析，提出了找矿方向，对外围找矿亦有一定的指导意义。 |

| Limestone of Maokou formation，middle Permian was found in Wanzi mining area，it proved that isolated platform existed in this area，the mining area located in the NE side of regional Hujiabao fracture and has typical ‘platform-fracture’ combined ore-control condition in west Guangxi. The mining area is a wide and gentle anticline structure，the orebody occurred in the strata of low Triassic of sedimentary unconformity interface，it is controlled by fracture zone and has the features of typical micro-grained gold deposit. The mining area is a wide and gentle anticline structure，the orebody occurs in the stratum of low Triassic on the sedimentary unconformity plane，it’s controlled by the fracture belt and has typical features of micro-grained gold deposit. By introduce the deposit mode of ‘The Second Floor’，the metallogenic condition and mineralizing information in this area are studied，then the prospecting direction is carried out and it will be helpful for out prospecting. |
