Three-Dimensional Localization Prediction of Deposit and Mineralization Environment Quantitative Assessment: A Case Study of Porphyry Copper Deposits in Sanjiang Region, China
The existing three-dimensional (3D) geological modeling systems rely heavily on large numbers of borehole and cross-section data. However, it is welt known that the available geological data are generally sparse and under sampled. In this paper, a new 3D system using block interpolation is implemented in Visual C++ 6.0 and OpenGL graphics library and is able to run on the PC platform. The important insights of 3D model of deposit are as follows:①Localization mechanism of deposit.②Three-dimensional interpolation method.③Mineralization environment. According to the three-dimensional model of Pulang deposits, the concealed orebody can be inferred, and the reserve of copper deposits can be evaluated with the copper tenor of the deposits. Based on the mineralization environment including preserve condition and denudation approach of porphyry copper deposits, the denudation amount and denudation speed of the deposits can be calculated. The results show that Cu reserve is about 8,500,000t in Yulong deposit, and that of 2,500,000t in Pulang deposit; the denudation rate of two deposits is 1.38t/a,1.22t/a respectively.
