Abstract

Abstract

The Zhangmajing U-Mo deposit, located in the Guyuan-Hongshanzi uranium mineralization belt, is a typical sub-volcanic hydrothermal deposit. Based on the summary and study of metallogenic geological body, metallogenic structure and metallogenic structural planes, alteration characteristics, fluid inclusion and isotope characteristics of the deposit, this paper constructs a "trinity" prospecting prediction model in the mining area. The model points out that under the condition of fault activity in the Early Cretaceous, the mantle-derived metallogenic thermal fluid mixed with atmospheric precipitation rose, activated the elements such as uranium and molybdenum in the old basement rock mass and Mesozoic acid rock, and metasomatized and precipitated to form disseminated low-grade mineralization. In the Himalayan period, the ore-forming hydrothermal fluid migrated and precipitated along the structural fracture zone in the upper and lower walls of the rock mass, forming vein-type U-Mo mineralization, Vein-type mineralization and disseminated mineralization are superimposed to form Zhangmajing uranium rich ore body. The establishment of the model lays a solid foundation for the breakthrough of ore prospecting in the metallogenic belt.
