摘　　要：江西南部金华寺测区位于南岭成矿带与武夷山隆起成矿带结合部位,属南武夷锰-锡-铜-金-银-铅-锌成矿亚带。在1∶2.5万沟系沉积物测量的基础上,选取异常较好地段进行1∶1万土壤地球化学测量,分析元素地球化学特征。针对测区内土壤地球化学元素异常较好地段进行岩石地球化学分析,进一步剖析其含矿性。结合野外地质调查,初步总结了测区内主要成矿元素的地球化学勘查模型及找矿方向。研究表明,金华寺测区Ag、Au地球化学异常明显,与断裂活动、辉绿岩脉关系密切;异常区具有一定的矿化,其中1号Ag异常地表矿化好,但深部找矿潜力有待查明。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 el?ement geochemical characteristics. Rock geochemical analysis was carried out in the good soil geochemical anomalous area to further an?alyze 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 a?nomalies, 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 poten?tial remains uncertain.
