摘要：
As an applied subject, the rock magnetism involves analyses of changes in magnetic properties of natural and synthetic minerals. Marine rocks and sediments contain magnetic minerals with different origins. Some key geological information, such as global climate changes, biomineralization, and earth dynamic evolution are preserved in these magnetic minerals. The variations of category, content, and domain state of magnetic minerals within marine samples can be resolved by rock magnetism, which provides abundant proxies for extracting related geological information. However, there are multi-solutions in the interpretation of rock magnetic parameters for marine samples due to the inherent complexities in magnetic mineral circulations and ocean internal processes, which prevents the well understanding of relevant geological information. The key to solving this problem is to better identify and quantify the magnetic minerals in samples. For this purpose, the main types of magnetic minerals in marine samples are described briefly, then this paper reviews the multi-solutions and matters needing attention for applications of rock magnetism in studies of category, content, and domain state of magnetic minerals in marine samples. At the same time, this paper looks forward to the prospects of limitations, emerging technologies, and future research strategy of rock magnetism. © 2024 Editorial Office of Chinese Journal of Geophysics.
