摘　　要：采用化学元素分析、偏光显微镜、电镜扫描下鉴定等综合手段,初步探明碳氟磷灰石的物相结构和碘的赋存状态。研究结果表明,磷块岩中的碘主要赋存在藻类磷质、淀晶磷质、胶磷质内,其中磷质基质填间的砂级内碎屑结构磷块岩含碘达190mg/kg。The features of C-Fluorine phosphorite and the distribution of iodine in phosphorus ore have been studied by use of combined means such as element analysis, microscope and electron-probe. The study shows that the iodine in phosphorus ore distributes mainly in abundant algal phosphorus, micro-phosphorus and cement-phosphorus and the content of iodine in sandy grade intraclastic phosphorus is up to 190 mg/kg.
