Abstract

The formation of structural alteration-type gold deposits is closely associated with tectonic activity and hydrothermal alteration processes. The accurate establishment of prospecting indicators and metallogenic models plays a crucial guiding role in mineral exploration. This paper systematically examines the material composition and formation conditions of structural alteration-type gold deposits, identifying three core categories of prospecting indicators: geological structures, mineral assemblages, and geochemical characteristics. By integrating the evolutionary behavior of metallogenic fluids, a metallogenic model characterized by “structural control of mineralization–fluid migration–alteration and mineralization” is established, and quantitative formulas for fluid metallogenic efficiency and alteration intensity are introduced to support the analysis. The results of this study can improve the accuracy of prospecting for this type of gold deposit and provide reliable theoretical and technical support for practical exploration activities.
