ANALYSIS ON THE CHARACTERISTICS AND ORE-CONTROLLING CONDITIONS OF THE XINZHAI-MAOCAOYUAN RARE EARTH DEPOSIT,LONGLING COUNTY
The granite weathering crust ion adsorption type rare earth deposit in Xinzhai-Maocaoyuan area,Longling County is controlled by both endogenous and supergene geological conditions,and mainly hosted in the middle and lower part of the whole weathering layer and the upper part of the strong weathering layer of the Cretaceous granite body.The distribution area of the V1-1 and V1-2 ore body is 38.59 km2 and 16.85 km2,respectively,and the single engineering-controlled ore body grade(SREO)of whichis0.035%-0.128%(with an average of 0.047%)and 0.035%～0.110%(with an average of 0.048%),respectively,reaching a large-scale prospective scale with a good prospect of exploration and development.
