| 摘 要： | 在典型矿床与区域成矿特征研究的基础上，系统总结云南沉积型磷矿的成矿地质、地球化学和岩相古地理特征，深入分析沉积型磷矿的成矿控制因素，建立了区域成矿模式。在此基础上，运用基于GIS的矿床模型综合地质信息预测方法对云南沉积型磷矿进行综合定位和定量预测，共圈定130个最小预测区，估算未查明的磷矿预测资源量121.98×108t。该成果对云南沉积型磷矿进一步的找矿工作具有重要的指导意义。

| Abstract: | Based on previous researches on characteristics of regional sedimentary type phosphorite mineralization and typical deposits, the authors summarized minerogenetic, geochemical and lithofacies-paleogeographic characteristics of sedimentary type phosphorite deposits in Yunnan Province and analyzed the major ore-controlling factors. On such a basis, a regional ore-forming model was established. The comprehensive localization and quantitative estimation of sedimentary type phosphorite resources in Yunnan Province were carried out by GIS-based deposit modeling comprehensive geological information prediction model. As a result, 130 minimum tracts were delineated, and potential resources amount was estimated at about 12.198 billion tons. These results are of significant indicative significance for further prospecting of this type of phosphorite resources. |
