Stability of Remanent Magnetization of Igneous Rocks

摘要: Summary Most tests of the magnetic stability a rock provide only crude evaluation. A better estimation could be obtained by measuring spectrum coercivities possessed rock; simple means obtaining coercivity is presented. It also shown that relation between distribution grain size and exists, not for prepared samples, but rocks as well. An evaluation sizes opaque grains effectively controlling properties must take account initial crystallization processes include consideration post-consolidation, high- low-temperature oxidation modifications. The development effective discussed. Results this study have provided additional insight into shape Js-T curve mineralogy.
