Magnetic Properties of Rocks and Minerals

TLDR: In this article, an updated collation of magnetic parameters of rocks and minerals for geologists, geochemists, and geophysicists is presented, and best-fit equations have been provided for some of the displayed ata so that interpolations can be made easily.

Abstract: This is an updated collation of magnetic parameters of rocks and minerals for geologists, geochemists, and geophysicists. Since the publication of the previous edition of Handbook of Physical Constants [74], two other collations have appeared [16, 18]. In addition, selected magnetic parameters have also been assembled [19, 22, 38, 41, 88]. Rather than produce a fully comprehensive collection, we have aimed for high-precision data obtained from wellcharacterized samples. Both tables and figures have been used for presenting the data, and best-fit equations have been provided for some of the displayed ata so that interpolations can be made easily. In an attempt to discourage the use of the outdated cgs system, all values are in the SI system (see Moskowitz, this volume). References have been cited for the sources used here. However, a more comprehensive bibliography has also been provided from which information can be extracted for samples which have not been included. The single-crystal constants and their variation with temperature and composition are for use by rock magnetists. Paleomagnetists and magnetic anomaly modelers have been provided with the magnetic properties of rocks and polycrystalline mineral samples. Lastly, we have made an effort to address the needs of environmental magnetism, a new group of researchers who require the values of sizeand
