Abstract

Abstract

The Zhuxi deposit is a new discovery of copper-tungsten dominated large-super-large ore deposit with great mineralization potential situated in the Zhuxi Area, Jingdezhen City, Jiangxi Province. However, present research is somewhat limited for some of the geological characteristics. Further study on genetic types and geochemical characteristics for this deposit is necessary. A bench-top type Polarized Energy Dispersive X-Ray Fluorescence Spectrometer, coupled with directly pressed powder samples has been used to analyze drill core samples of the Cu-W ore body. The instrument used in the experiments has a high detection ability for measuring major elements (SiO₂, CaO and MgO) and trace elements (Cu, W, Zn and Ag), compositions with low detection limit, small error, good stability and other characteristics. The experimental results show that the major elements of SiO₂, CaO and MgO have strong metasomatism characteristics. The SiO₂ and CaO have a negative correlation. Trace elements Cu, W, Zn and Ag also exhibit symbiotic features, and Cu, W contents are high in the middle and low on both sides spatially. All evidence explains the metasomatism characteristics controlled by structures. The element variations and related mineral compositions also indicate that ore-forming materials were derived from granodiorite, porphyry, granite porphyry and diorite. These results provide a theoretical basis for mineralization forecast and further exploration goals.
