| 摘 要： | 织金新华磷矿是我国扬子地台西南缘早寒武世重要的海相沉积磷矿床.长期以来,织金磷块岩磷酸盐矿物成分被认为是碳氟磷灰石或低碳氟磷灰石,有学者认为,产于沉积岩中的磷灰石基本上都属于碳氟磷灰石.本文利用电子探针的微区成分定量分析技术和x射线衍射分析技术,确认织金磷矿碎屑磷灰石为氟磷灰石.

| Abstract: | Zhijin Xinhua phosphate deposits is an important marine sedimentary phosphate deposits formed in Early Cambrian Epoch located in South-west edge of Yangtze Platform.For decades,the mineral composition of phosphate in Zhijin Xinhua phosphate deposits is considered to be Carbonatefluorapatite or low-Carbonatefluorapatite.Some researchers believe that almost all of the apatite formed in sedimentary rocks belong to Carbonatefluorapatite.In our study,by using of the technique of electron probe microanalysis(EPMA) and X-ray diffraction,we found that the mineral composition of the clastic phosphate in Zhijin phosphate deposits is fluorapatite.This results may provide some useful information for the study of metallogenesis of the Zhijin Xinhua phosphate deposits. |
