安徽宿松县柳坪磷矿地质特征及找矿标志

Geological characteristics and prospecting marks of Liuping phosphate deposit in Susong County,Anhui

柳坪磷矿是宿松地区典型磷矿床之一,其矿床资源储量规模达中型,其磷矿赋存于宿松岩群的柳坪岩组中,分为上下四层。该磷矿为“海州式”沉积变质型矿床,受岩层和次级褶皱的控矿条件制约,具有地层、岩性组合、磷锰共生、地球化学异常等找矿标志。矿区部分地段深部延伸稳定且未完全控制,显示深部仍然具有较大找矿潜力。

Liuping phosphate deposit is one of the typical phosphate deposits in Susong area,and its resource reserve scale is medium.Phosphate orebody is hosted in Liupingite Formation of Susong Rock Group,which is divided into four layers upper and lower.The phosphate deposit is sedimentary metamorphic phosphate deposit of"Haizhou type",limited by ore-controlling conditions in rock strata and secondary folds.There are typical prospecting marker characteristics such as stratum,lithological assemblage,phosphorus and manganese symbiosis,geochemical anomaly.The deep extension of some ore sections is stable and not fully controlled in the mining area,indicating that there is still a great prospecting potential in the deep area.
