Three-dimensional geological modeling can effectively present the three-dimensional spatial distribution and visualization of geological bodies,structures and their interrelationships,therefore it can provide important reference for deposit prediction and has great effects on discovering concealed ore bodies in deep and peripheral areas of the mining districts.Based on the works of collecting and processing geological,drilling and geophysical exploration data of Xiaejing uranium deposit,three-dimensional geological models of the deposit's drilling,strata,lithology and color of strata,mineralization bodies and geophysical logging were established in this paper using the GOCAD modeling software.Together with the integrating regional geological conditions for mineralization,mineralization laws and the theory of sandstone-type uranium mineralization through permeation,a comprehensive analysis of the three-dimensional geological model was conducted.The northeastern part of the study area was found with favorable geological conditions and exploration potential for mineralization,and promising for deep exploration.The research results provided a basis for the next stage of uranium exploration prediction and mineral exploration in Nanxiong Basin area,which has significant theoretical and practical significance for mineral exploration.
