Remanent magnetism of poorly sorted deposits from the Minoan eruption of Santorini

Thick, poorly sorted ash deposits produced during the Minoan cruption have differing palacomagnetic histories. Included clasts from deposits produced in the second phase of the eruption have random NRM and cleaned directions and were emplaced as cold mudflows. Clasts from ignimbrite flow units erupted in the third phase have significant directions and their palacomagnetic pole is consistent with today’s geomagnetic pole. These deposits acquired a TRM on deposition and were emplaced as hot pumice flows.
