Abstract

The ore body of Shazhou deposit in Jiangxi Province is strictly controlled by faults and its wall rock alteration zoning characteristics is very apparent. This paper introduces the geochemical characteristics of the wall rock alteration. The results of whole-rock analysis of Shazhou deposit show that the chemical composition of the ore body is very different from the surrounding rock and the differences are relevant with the migration of chemical elements in the course of alteration. The combinations of metallogenetic elements are U, W, HREE, Th, Zn, Zr, Mo, Pb based on R-mode cluster analysis of all the rock samples and these elements can serve as the criteria for U ore prospecting in the region.
- Shazhou deposit,
