| 摘 要： | 磁性矿物的组成和颗粒粒径的分布决定了岩石或沉积物的基本磁学性质及其所携带的天然剩磁在地质时期内的稳定性.由于自然界中磁性矿物的复杂性和多样性，如何有效的确定磁性矿物的成分和粒径分布一直是岩石磁学的基础和难点.本文对确定磁性矿物成分和粒径分布的常见方法进行了较为详细的总结和分析，并对常见磁性矿物在高温和低温下的磁学性质进行了详细的论述.最后对如何应用综合方法判定样品中的磁性矿物种类以及粒度分布进行了探讨.

| Abstract: | The magnetic properties of rocks or sediments and the stability of their natural remanent magnetism are determined by the composition and grain size of the magnetic minerals.However,because of the complexity and variety of natural magnetic minerals,how to effectively identify the composition and grain size of the magnetic minerals is always the foundation and difficulty of rock magnetic studies.This paper is a detailed review of the approaches which have been developed to identify the composition and grain size of the magnetic minerals.The high and how temperature magnetic properties of common magnetic minerals are described.Finally we will discuss how to use combined technique to characterize the composition and grain size of the magnetic minerals. |
