摘要
龙陵新寨-茅草园地区花岗岩风化壳离子吸附型稀土矿床受内生地质和表生地质条件双重控制,主要赋存于白垩纪花岗岩体全风化层中下部及强风化层上部,V1-1矿体分布面积 38.59km2,单工程控制矿体品位(SREO)0.035%～0.128%,平均 0.047%;V1-2 矿体分布面积 16.85 km2,单工程控制矿体品位(SREO)0.035%～0.110%,平均 0.048%,达大型远景规模,具有较好的勘查开发前景.
Abstract
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.
