摘　　要：江南隆起成矿带(江西段)位于江西省北部修水至都昌一线,带内自然重砂异常呈北东东向展布,与区域构造线一致,受花岗岩、已知矿产和自然地理条件控制。根据地质构造背景及自然重砂异常空间分布特征,进一步划分2个自然重砂异常带和8个自然重砂异常集中区。区内自然重砂异常展现了矿产资源的潜在前景,为开展矿产资源调查与评价提供重要的重砂异常标志。The Jiangxi section of the Jiangnan uplift metallogenic belt is located between Xiushui and Duchang area in the north Jiangxi Province. The mineral anomalies in the belt,distributing as NEE -trend which is consistent with structural lineation, are significantly controlled by granite, known mineral resources and natural geographical conditions. According to the geological conditions and spatial distribution characteristics of the natural heavy minerals, two natural heavy minerals anomaly belts and eight natural heavy minerals concentrations are divided in this paper, showing the potential prospects of mineral resources and providing important natural heavy minerals anomaly information for mineral resources survey and evaluation.
