Abstract
- A new tungsten-copper deposit with large-super mineralization potential was recently discovered in the Zhuxi area, Jingdezhen city of Jiangxi Province. The primary halo research plays a very important guiding role in further exploration work. By using Polarized Energy Dispersive X-ray Fluorescence Spectrometry, Inductively Coupled Plasma-Mass Spectrometry/Atomic Emission Spectrometry, large amounts of sample analyses have been conducted. According to the contents of elements W, Sn, Bi, Mo, Pb, Zn, Cu, As, Sb and Ag, these are served as the indicators of the primary halo. The primary halo of Zhuxi tungsten-copper deposit shows that Cu, Zn, Ag and Pb have good correlation as well as W, Bi, Sn and Mo. W is also correlated with Cu. The ore-forming elements have some characteristics in space. In the same section, high temperature elements such as W are more enriched at the northwest, whereas in the plane, this performance appeared at the southwest. Overall, W-oriented high-temperature elements are more enriched at lower depths. By comparison, Cu-oriented middle-temperature elements are shallower than W. This study indicates that the Cu deposit is distributed in the medium deep part (-1400--1500 m), W deposit in the deep part (-1400--1900 m) and Ag, As, Sb at the surface (-1100--1200 m). This study provides a theoretical basis for mineralization forecast and further exploration.
