Abstract
- Various magnetic measurements were carried out to diagnose magnetic mineralogy of the ferromanganese crust obtained in the Magellan Seamounts, the West Pacific (~20°N). Thermal demagnetization revealed a Curie temperature of ~560oC, corresponding to (titano)magnetite. Component analysis of isothermal remanent magnetization identified a presence of two types of magnetite. Measurements of first order reverse curve showed a dominance of non-interacting single-domain magnetite, which is one of the intrinsic feature of biogenic magnetite.ponding to (titano)magnetite.
