Jinzhuchong copper deposit in Jinping county of Yunnan province is on the suture zone between the Qinghai—Xizang(Tibet)—Yunnan plate and Yangtze plate, which belongs to the southeast section of the Ailao Mountains metamorphic terrane. The area is among the crust accretionary belts of the Ailao Mountains metamorphic terrane which is chiefly composed of high-grade metamorphic rocks. The deposit is located in a vegetable-covered high mountain area with big topographic relief, where exploration is a difficult problem. This paper takes this deposit as an example and comprehensively applies high-precision magnetic survey,dual-frequency IP and EH4 to do prospecting work. The geophysical was worked out according to soil geochemical exploration and geological information. In this way the paper has predicted favorable mineralization targets and then done effective engineering test. The result shows that the deposit has vast metallogenic potential, and the fast prospecting model in vegetable-covered high mountains was initially established in southern section of the Ailao Mountains.

The Haoyihada intrusive body,which occurred in the continental margin accretion belt along the north margin of North China Plate in the middle region of Inner Mongolia,is composed the pyroxene diorite. With isotopic dating and geochemical research,the zircon LA-ICP-MS U-Pb dating of two samples yields an age of 266±2 Ma,failing into the range of late Permian Epoch. The geochemical characteristics of 14 samples are as follows,the pyroxene diorite shows low-SiO_2(47.87～56.17 wt%),high-Mg(3.65～6.79 wt%),also higher large-ion lithophile element of Rb,Sr and LREE,low high-field strength elements of Nb,Ta,high-Cu(35.97×10~(-6)～112.24×10~(-6)),REE patterns have negative Eu anomalies. It is suggested that the Haoyihada intrusive body should be among the calc-alkaline series,has the tectonic background of island-arc and its materials mainly derived from upper mantle and had fractional crystallization. The geochemical characteristics and the strong mineralization of Cu and W of Haoyihada intrusive body prefigured that the potential of ore prospecting and exploration is great in this area.

3D modeling and visualization of geology volume is very important to interpret accurately and locate subsurface geology volume for mining exploration and deep prospecting. However, it faces a lack of information because the target area is usually unexplored and lacks geological data. This paper presents our experience in applying a 3D model of geology volume based on geophysics. This work has researched and developed a 3D visualization system. It is based on an OO (orientated object) approach and modular programming, uses the C++ language and Microsoft .NET platform. This system has built first a high resistivity method and MT database. The system uses irregular tetrahedrons to construct its model and then finally has built the 3D geological model itself.
