Abstract:

The mineral potential assessment of 25 important mineral resources has been the most important prediction by far in China. In this projection, methods of deposit model and integrated geological information are used to predict mineral resource potential. Some methods are put forward to solve some difficulties in mineral prediction such as lack of unbalance of geological works, 3D prediction, integration of qualitative prediction with quantitative prediction, as well as data integration of geology, geophysics, geochemistry and remote sensing. During the prediction work, we put forward some methods as followings. Firstly, sedimentary formation is linked with metallgenitic settings by using type of mineral prediction to compile Formation-Tectonic map. Secondly, the quantitative prediction model can be founded by studies on deposit model and prediction factors. Thirdly, the transformation from 2D to 3D is completed by using geological parameter volume method to estimate resources.
