摘要
Objective Three-dimensional(3D)subsurface geological models have been gaining considerable attention wordwide.3D geological surveys and modelling in the Xiangshan uraniferous volcanic basin,Le’an county,Jiangxi Province is a pilot project of the China Geological Survey.The Xiangshan volcanic basin is the third largest volcanic-type uranium ore field worldwide.This basin is composed of Lower Cretaceous rhyodacite and porphyritic lava with shattered phenocrysts,as well as small amounts of high-level intrusive acidic rocks,overlying a basement of metamorphic rocks.More than 60 years of exploration and mining activities have revealed the most important geological characteristics and factors controlling the uranium mineralization。
