| [Objective] Wugongshan area in western Jiangxi Province is an important rare metal and non-ferrous metal ore concentration area in Jiangxi Province. It has superior metallogenic geological
conditions and is a favorable area for prospecting breakthroughs in strategic minerals such as lithium, tantalum, niobium and tungsten. Based on the results of 1∶50 000 stream sediment survey, this paper analyzes and studies the distribution and combination characteristics of elements, enrichment and dispersion rules, and their relationship with metallogenic geological conditions in the eastern margin of Wugong in western Jiangxi, and delineates 25 comprehensive anomalies and carries out anomaly verification work. After anomaly verification, 10 ore ( mineralization ) points of lithium, tantalum-niobium, gold and other types were newly discovered, and 4 tantalum-niobium ore ( mineralization ) bodies, 1 lithium mineralized body and 3 gold ore bodies were newly discovered. The geochemical anomalies of Li, Ta, Nb, W and Au in the eastern margin of Wugong have a good indication effect on prospecting. Most of them are ore-induced anomalies, which are mainly formed in the metallogenic process of altered granite-type rare metal deposits, micro-disseminated gold deposits, metamorphic clastic rock superimposed tectonic hydrothermal gold deposits and quartz vein-type tungsten deposits in the study area. The anomaly characteristics indicate that in addition to the known ore ( deposit ) points, the prospecting potential of rare metals, tungsten and gold deposits in the study area is still huge. According to the anomaly characteristics, combined with previous research results, five prospecting areas are divided in the eastern margin of Wugong, which provides a reference for the optimization of strategic mineral target areas and the next geological prospecting work in this area. |
