porphyry deposit in the eastern part of central Gangdise, found in recent years(Tang et al., 2010). In the comprehensive research of ore deposit, there are a large amount of work, such as geological characteristics, alteration-mineralization characteristics, the rock forming and ore-forming chronology, fluid evolution, the source of ore-forming materials, and so on (Tang et al., 2010;Zheng et al., 2010; Guo et al.,2012; Ying et al, 2014; Zhou et al., 2011; Li et al., 2012). But in the latest of deposit model building did not completly report. 3D models are forced to respect predefined constraints to obtain the required accuracy and allow detailed integration of datasets; moreover, they permit rapid multi-scale structural analysis of data; the virtual reconstruction of an ore deposit also enables faster visualisation of geometrical characters and intensive spatial analysis of large databases; making 3D model is not only visualization of geological, but also a scientific tool, and both for mineralization and alteration on space distribution study, a summary of the ore deposit genesis and the metallogenic law, or mineral exploration has extremely important significance(de Kemp, 2000; L.Feltrin et al, 2009). Based on MICROMINE 3D modeling and visualization technology, according to the latest exploration and research, this study constructed Jiama three-dimensional model, which directly shows the distribution of strata, rock, tectonic and fu seam position, provide important scientific basis for the genesis of Jiama ore deposit, summarizing the metallogenic regularities, prospecting exploration and mining production, and so on.
