| 摘 要： | 白登磷矿是我国重要的浅海相磷块岩矿床，而青龙哨磷矿是我国重要的陆相磷块岩矿床.两地磷矿品位高，储量大，是滇池地区正在开采的2个重要磷矿基地.野外工作研究发现，青龙哨角砾状磷块岩顶板的磷锶铝石矿层和高岭土黏土岩二者呈超覆式不整合接触.深入研究发现其具有陆相磷块岩的许多特征，而没有浅海相磷块岩的原生沉积构造特征.同时，白登磷矿见上下2层工业矿体，而青龙哨磷矿仅见1层工业矿体.对此二矿床特点进行了对比分析.

| Abstract: | The Baideng phosphorite deposit is of shallow-sea facies;while the Qinglongshao phosphorite belongs to continental facies.Both of them are important phosphate ore mining bases in Anning,Yunnan Province,with high grade and big reserves.The goyazite ore bed and kaolin claystone unconformably overlap the Qinglongshao breccia phosphate,which is characterized by continental facies phosphorite,without the shallow-sea characters of primary sedimentary structure.The Baideng deposit contains two layers of commercial ore;while the Qilongshao deposit includes only one layer. |
