Sedimentary Characteristics and Mineralization Prediction of the Doushantuo Period Phosphorite in Weng'an,Guizhou
Weng'an,located in Guizhou Province,is an important mineralization area where proven phosphate rock resource reserves are 3.65 billion tons during the Doushantuo period.With the implementation of a new round of prospecting breakthrough strategic actions,it is urgent to predict the phosphorus formation conditions and prospecting prospects in Weng'an area and guide the phosphate prospecting work.On the basis of comprehensive analysis of regional geology,regional distribution of phosphate bearing rock series,lithofacies paleogeography,and ocean current direction,it is proposed that Weng'an compound anticlines are favorable for phosphorus mineralization.Therefore,seven phosphorus prediction areas have been delineated,including Zhongping,Jianzhong,Nanzhai,Pingdingying,deep part of Weng'an syncline,Languan and Caotang areas,which may contain medium to large and ultra large phosphorus deposits.
