摘要
Magnetic properties of minerals in natural rocks or sediments are controlled by many factors, such as magnetic species, grain size, shape, interactions, and the hosting environment. Conventional experiments of rock magnetism can hardly decouple the effects of these factors on the magnetism of minerals. In this study, we review studies of magnetic properties of rocks by combining rock magnetic experiments with micromagnetic modeling approaches. Firstly, principles and history of micromagnetic modeling are briefly introduced. Then, two basic topics in paleomagnetism, including effects of physical constraints and environmental modification of magnetic grains on magnetic behaviors are discussed in terms of micromagnetic modeling. Finally, we propose directions in which micromagnetic modeling is likely to develop in the future. In all, micromagnetic modeling of magnetic grains provides a further understanding of magnetic minerals in geological processes.
