Abstract：Most of gold mineralizations are related to hydrothermal fluid activity. During the migration and evolution of the fluids in the ore-forming process, fluid would extensively reacted with wall rocks and precipitated gold at suitable tectonic space,resulting in alteration minerals in the pathways. Such alteration minerals were formed under certain conditions so that their association could be used to represented the changing of physical-chemical condition during mineralization and be used as prospecting vector. Therefore, all characteristics of mineral formed in the process for identifying ore-forming condition are called mineral typomorph. In terms of mineralization alteration and its spatial distribution related to gold mineralization, and typical mineral properities (such as thermoelectricity of gold-bearing pyrite, short wave infrared spectroscopy and magnetic susptibility of altered minerals, and so on), mineral zonation and alteration mapping can establish mineralization and exploration models. These models could be useful for further ore prospecting. In this study, we compared the characteristics of mineral alteration and typomorph in some gold deposits. The results suggest that typomorph-based mineral mapping is a power tool for lessening target area and ore prospecting.
