摘　　要：剥蚀—沉积平衡机制是重矿物在地表环境下迁移富集的基本规律。结合有关应用实例,从重矿物迁移、富集规律出发,以动态、逆向的工作思路,提出对以往自然重砂数据进行整理、重新圈定重砂异常的工作方法。在矿产资源调查工作中应充分发挥自然重砂测量这一传统找矿方法的优势,以期找到更多的矿产资源。As shown by previous researches, the denudation-accumulation balance mechanism is an essential rule of the transforming and accumulating behavior of natural heavy minerals at the surface. Based on some application examples and the rule of transforming and accumulating behavior of heavy minerals, this paper tries to sum up the method for sorting out heavy mineral data and re-delin？eation of heavy mineral anomalies by way of dynamic and reverse ideas. The authors aim to put forward a better prospecting method which brings placer prospecting into full play.
