陆源砂中重矿物的数量与成分是沉积物的重要特征。按的见解,“……现代海洋沉积物中重矿物的数量是确定形成沉积物的水动力学状态的主要参数之一,是主要的找矿标志”。研究重矿物在平面和剖面上的分布,可以完成一系列普查找矿与普通地质学方面的任务,其中包括砂矿与原生金属矿床的普查,哑地层的地层学对比,海洋冲积层的动力学,新构造学与古地理学等。要完成这些任务
The quantity and composition of heavy minerals in terrigenous sand are important features of sediments. According to the opinion, “... the amount of heavy minerals present in modern marine sediments is one of the main parameters in determining the hydrodynamic state of sediment formation and is the major indicator of prospecting.” Studying the distribution of heavy minerals in both horizontal and vertical planes can accomplish a number of tasks in general prospecting and general geology, including the census of placer deposits and primary metallogenic deposits, the stratigraphic contrast of dull strata, the dynamics of marine alluvium , Neotectonics and Paleogeography. To accomplish these tasks
