Abstract

Abstract

The Xiangshan ore field is the largest volcanogenic uranium ore field in China with abundant uranium resources and favorable geothermal geological conditions. However, few studies have been conducted on its thermal structure and mineralization characteristics,In order to solve this problem effectively. Taking the Zoujiashan super-large uranium deposit in the west of the ore field as a typical area, this study systematically investigated the thermal structure characteristics of the ore field, established the thermal structure model, and analyzed the relationships between heat generation and mineralization. The results are as follows. The thermal structure in the study area is of the hot-mantle and cold-crust type, which is in line with the characteristics of thermal structures in eastern China. The higher crustal heat flow in the area is closely related to the uranium source and uranium ore bodies, and the decay heat generation of radionuclides is the main source of the crustal heat flow. The thermal anomalies in the area are obviously controlled by faults, and the heat source is highly consistent with the uranium source. The geothermal gradient anomalies are one of the prospecting criteria of the area. Moreover, 4 ℃/100 m is the positioning marker of deposits, and the variation amplitude of geothermal gradients can be used as the positioning marker of rich and large ore bodies. This study provides effective technical support for the study of geothermal geology and metallogenic geology in this area.
