Three-dimensional structural characteristics of the Zhaxikang ore-concentration area based on multiple attribute constraints

Abstract

The Zhaxikang ore-concentration area (ZOCA) is in the Gangdese metallogenic belt in the southern Tibet Plateau. It has huge prospecting potential. Most of the mineral resources on the Gangdese metallogenic belt are controlled by the dome and fault. The deep structure and the coupling relationship between the Cuonadong dome and the deep structure are of great significance for understanding ore-controlling structures and hydrothermal channels. Existing studies have been controversial in the study of whether there are hidden structures in the deep part of the Zhaxikang deposit, and whether the Cuonadong dome extends to the bottom of the Zhaxikang deposit in the Gangdese metallogenic belt. Therefore, we comprehensively analyzed a large number of gravities, magnetic, and magnetotelluric data in the Zhaxikang area and carried out a fusion display of multiple information in the Zhaxikang ore-concentration area. Understand the relationship between the Cuonadong dome, fault system and deep hydrothermal channel through fusion display to analyze the background of Zhaxikang metallogenesis. The deep structure of the Cuonadong dome was identified, and it was found that there was a hidden structure at the bottom of Zhaxikang that was not connected to the Cuonadong dome. These findings are a great significance for further theoretical research and breakthroughs in ore prospecting.
