CHARACTERISTICS AND DISTRIBUTION PATTERN OF THE MENGBANG RARE EARTH ORE BODIES IN TENGCHONG,YUNNAN
The Mengbang rare earth deposit in Tengchong belongs to the ion adsorption type deposit of granite weathering crust.The ore body is distributed in the fully weathered layer of the weathering crust of the late Yanshanian biotite monzonitic granite body,which is affected by the topography and undulates with the topography.The overall distribution is planar along the ridge,and the plane is irregularly banded.In this paper,the ore-controlling factors and ore body genesis are preliminarily discussed by analyzing the development characteristics of granite weathering crust and the geological characteristics and distribution rules of rare earth deposits in the mining area.It provides reference for the exploration of rare earth deposits in adjacent areas with similar metallogenic geological background.
