Title: Rock magnetism of the Early Pliocene Trubi Formation at Eraclea Minoa (Sicily)

Abstract

The most important magnetic mineral in the fine-grained marls of the Early Pliocene Trubi formation near Eraclea Minoa is magnetite. Some geothite is also present. The magnetite is of high purity and of primary origin. Hysteresis and low-temperature measurements show that most magnetite grains are single-domain. The presence of superparamagnetic grains is suspected. Multi-domain grains are rare. It is shown that AF demagnetization does not yield correct NRM directions.
