摘要: 在龙州地区首次发现早石炭世的堆积型铝土矿矿源层,提出广西堆积型铝土矿至少存在早石炭世和晚二叠世两个时代的矿源层。探索运用高密度电阻率法寻找古风化壳沉积型铝土矿的有效性试验工作。提交新发现矿产地4处,探获新增铝土矿(3341)资源量5 289.15万吨。重新厘定区域地层岩性及岩相特征,系统总结区内铝土矿矿床(点)的时空分布特征、控矿地质条件、成矿规律及找矿标志,建立了区域成矿模式和预测找矿模型,圈定成矿远景区5处,找矿靶区6处,开展区域矿产预测,初步评价了本区铝土矿资源潜力。为该地区下一步地质调查、矿产勘查规划和开发提供了丰硕的基础资料和有益参考。Abstract: In this project, we discovered a new accumulation type bauxite source bed of early Carboniferous in Longzhou district, and proposed that there were at least two metallogenic epochs of accumulation type bauxite source beds in Guangxi which were early Carboniferous and late Permian. We tried to search for ancient weathering crust sedimentary bauxite by using the high density resistivity method of prospecting effectiveness test work. We submitted 4 newly discovered mineral lands, and figured out 52 891.5 kilotons of bauxite resources (3341). We redefined the regional stratigraphic lithology and facies characteristics, and summarized the bauxite deposits (occurrences) temporal and spatial distribution characteristics, controlling ore-forming geological conditions, metallogenic regularities and prospecting criteria. We established the regional metallogenic model and prospecting model, delineated 5 metallogenic prospective areas and determined 6 prospecting target areas. In addition, we forecasted the prospecting potential of bauxite in the Fusui-Chongzuo district,Guangxi. All these progress and achievements provide fruitful basic materials and beneficial reference for further geological survey, mineral exploration and development.
