    Three dimensional geological modeling technology of multivariate data in deep mineral survey: An example from the Tongling ore cluster area

    • Deep mineral and geological survey focuses on studying deep geological structure and searching for deep concealed or semi-concealed ores and the mines which are difficult to identify. Combined with the characteristics of deep mineral investigation, a 3D geological modeling technique, which is also suitable for modeling of ore cluster areas, is proposed in the paper based on database, 3S, 3D modeling, and 3D visualization technology. According to the full-scale geological survey data and the metallogenic system theory, this method developed a model which combines ore cluster area, ore field and deposits together using multiple data parallel sections modeling. This model couples with ore-bearing geological bodies and their spatial distribution in the study area, realizing the “transparent” manifestation of the shallow 3D metallogenic system structure in the ore cluster area with a depth of 2 000 meters. The 3D modeling technique can provide an important support for verifying metallogenic model, extracting ore-forming data and constructing 3D exploration prediction. The technique has been verified and achieved good results in Tongling, thus providing reference for prospecting the deposits of the same kind in other areas.
