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。
江西南部金華寺測區位于南嶺成礦帶與武夷山隆起成礦帶結閤部位,屬南武夷錳-錫-銅-金-銀-鉛-鋅成礦亞帶。在1∶2.5萬溝繫沉積物測量的基礎上,選取異常較好地段進行1∶1萬土壤地毬化學測量,分析元素地毬化學特徵。針對測區內土壤地毬化學元素異常較好地段進行巖石地毬化學分析,進一步剖析其含礦性。結閤野外地質調查,初步總結瞭測區內主要成礦元素的地毬化學勘查模型及找礦方嚮。研究錶明,金華寺測區 Ag、Au 地毬化學異常明顯,與斷裂活動、輝綠巖脈關繫密切;異常區具有一定的礦化,其中1號 Ag 異常地錶礦化好,但深部找礦潛力有待查明。

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.
