Abstract Located at the junction of the Nanling metallogenic belt and the Wuyishan metallogenic belt, Jinhuasi surveyed area in southern Jiangxi belongs to the South Wuyi manganese-tin-copper-gold-silver-lead-zinc metallogenic subzone. On the basis of 1:25,000 gully sediments survey, the good anomalous segments were selected to conduct 1:10,000 soil geochemical survey for analyzing element geochemical characteristics. Rock geochemical analysis was carried out in the good soil geochemical anomalous area to further analyze its mineralization. Combined with field geological investigation, the authors preliminarily summarized the geochemical exploration model and prospecting orietation of the main ore-forming elements. Studies show that Jinhuasi surveyed area has Ag, Au geochemical anomalies, which are closely related to fault activity and diabase veins. The mineralization of the anomalous area is promising, with the surface mineralization of the first Ag mineralization anomalous surface being most excellent; nevertheless, the deep prospecting potential remains uncertain.
