Searching for single domain magnetite in the "pseudo-single-domain" sedimentary haystack: Implications of biogenic magnetite preservation for sediment magnetism and relative paleointensity determinations

Roberts, Andrew; Chang, Liao; Heslop, David; Florindo, Fabio; Larrasoana, Juan

Description

Magnetic hysteresis measurements of sediments have resulted in widespread reporting of "pseudo-single-domain"-like magnetic properties. In contrast, the ideal single domain (SD) properties that would be expected to be responsible for high quality paleomagnetic records are rare. Determining whether SD particles are rare or common in sediments requires application of techniques that enable discrimination among different magnetic components in a sediment. We apply a range of such techniques and...[Show more]
