Abstract:

analyzing oreforming information of Lutangba study area in Gejiu, Yunnan Province, authors made a prediction of blind ore body with the help of 3D visualization technology. We took the stratigraphy and fracture as mainly orecontrolling factors according to geological feature and mineralization law, constructed digital deposit model by means of  3D modeling software. Advantageous factors of oreformation are extracted, including stratigraphy, fracture, quantitative information of structures and chemical elements abnormal as predictive variable by using method of the cubic predicting model. And finally we utilized delineate prospect area and then outline 4 targets. The prospective areas show that the study area has a good potential for prospecting minerals and the method of ore prediction is very effective. The application of the analysis method which is quantitative information of structures as new prospecting variables achieve a new breakthrough in 3D prospecting minerals.
