磁铁矿单矿物研究现状、存在问题和研究方向

Study of Magnetite: Problems and Future

磁铁矿在自然界分布广泛,是重要的成岩矿物和矿石矿物。磁铁矿的物理化学特征一直是研究的热点,尤其是近年来随着单矿物激光ICP-MS测试技术的成熟,利用磁铁矿的微量元素特征进行矿床成因机制研究已成为矿床学研究的前沿,已取得一系列成果。本文对这些成果进行了综述和介绍,同时也指出在开展这一研究中面临的主要问题,如分析方法不一致,缺乏重要的铁矿床类型实例,物理结构研究薄弱和勘查应用研究亟待加强等,并认为这些问题的解决应是今后开展磁铁矿研究的重要方向。

Magnetite occurs widely in nature and acts as an important mineral for rock-forming and ore. Intensive studies have been conducted on its physical and chemical features. With the development of new technique on single mineral analysis,such as Laser ICP-MS,exploring the ore genesis using trace elements of magnetite is becoming a frontier field of ore deposit study,and numerous excellent results have been achieved in recent years. However,a series of problems have been recognized,such as the inconsistent of analytical methods,lack of important Fe deposit types,little attention on mineral structures and weak application on mineral exploration. Nonetheless,these problems also point out the directions for the future study on magnetite.
