摘要
采用化学元素分析、偏光显微镜、扫描电镜Jeol-Jsm-6460//lvSEM和EDAX能谱仪等手段进行了综合鉴定,结果表明,磷块岩中的碘元素不是以独立矿物形式存在,而是以类质同象形式存在于磷灰石中藻类磷质、淀晶磷质、胶磷质内。这些磷质中的含碘量占磷块岩中含碘量的98%以上,其中磷质基质填间的砂级内碎屑结构磷块岩含碘高达190mg/kg-矿,磷块岩的脉石矿物中含碘量仅为1×10-4%～2×10-4%。
The results of comprehensive analysis carried out with the help of chemical dement analysis, polarized light microscope, Jeol-jsm-6460//lv SEM-（ Scan of Electronic Microscopy） and EDAX- （Energy Di-spersive Analysis of X-ray） and other means of observation showed that the iodine element in phosphate does not exist in an independent form of mineral and mostly in algae phosphorus in apatite, precipitated crystallization phosphorus, collid phosphorus in quality isomorphic form. Iodine in the phosphate accounts for 9896 and more of the phosphate rock , Iodine in intraclastic phosphorus of phosphorus matrix of the sand-filled within is as high as 190 mg/kg-mine. Iodine is only 1--2 ppm in the gangue minerals of phosphorus
