The Lujing uranium deposit is a large scale granite-type uranium deposit in the Lujing uranium orefield,Hunan-Jiangxi border.Multi-source information of the Lujing uranium deposit was systemically collected and pre-processed to construct database and 3D geological model for visualization,which concludes geology,drilling-hole, geophysics and geochemistry information.Methods:In this paper,the methods include 3D distance buffer analysis and 3D morphology analysis for extracting ore-controlling factors were used to quantificationally determine the affection rang of structure,interfaces between different rocks and intrusion surface of uplift or depression.Meanwhile,3D weights of evidence was applied to delineate targets based on quantitative analysis of ore-controlling factors and anomalies.Results:Three targets were identified,and the resources estimation is several hundreds tons.Conclusions: Based on 3D geological modeling technology and 3D spatial analysis technology of ore controlling factors,visualization of sub-surface,spatial relationship between geological objects(hosting strata，intrusion and structure), anomalies and minerlization are clearly observed.therefore we can construct prospecting model for the study area.Though the calculation of the weights of ore controlling factors and the posterior probability of the cube,the concealed orebody in depth are identified.It is confirmed that there is a certain metallogenic potential in the depth of the study area and it provides strong support for further exploration.
