自然重砂的应用现状与前景

自然重砂测量作为一种经济实用的找矿方法，在20世纪60—80年代随着区域地质调查工作而系统地展开，积累了大量的数据，然而这些数据的系统整理却是在近10年的全国矿产资源潜力评价项目实施过程中完成。针对自然重砂的特点，概述了目前的研究现状，分析了自然重砂找矿方法的应用前景及存在问题，认为自然重砂矿物及其组合将会针对多种矿产包括金银多金属、黑色金属和部分非金属直接用于地质找矿，界定矿床成因类型，寻找可能存在的特征性岩体，解决区域岩石学问题，判别特殊构造类型，辅助研究区域构造格架，并提出了自然重砂方法及资料应用建议。

APPLICATION AND OUTLOOK OF HEAVY MINERALS

Heavy minerals survey as an economic prospecting had been widely applied during 1960 to 1980 with regional survey. It accumulated large quantity of data, which had been systematically processed in recent ten years during national mineral resource assessment project. This paper analyzes its issues and outlook of heavy minerals prospecting, concludes that heavy minerals and their combination indicate many kinds of metals deposits including gold and silver, black metal and partial non metallic minerals, determine the genesis of deposits, and look for possible magmatic intrusions. It also can be used to study regional petrology, structures, regional structural framework. This paper presents approaches to heavy minerals and data application.
