Scientific paper

The LL6 St. Severin possesses an ancient stable natural remanent magnetization (NRM), whose higher unblocking fractions (520-560°C) are randomly oriented yet lower unblocking fractions (<520°C) form a potential magnetic foliation. The St. Severin contains paramagnetic troilite, Cr-Fe-Ti-oxide and potentially ferromagnetic Fe-Ni system. A sharp unblocking around 560°C during thermal demagnetization strongly indicates that tetrataenite is the sole remanence carrier in the St. Severin. However, the absence of ferromagnetic signal in kamacite and the presence of a randomly oriented higher unblocking fraction (520-560°C) of NRM for tetrataenite indicate a multi-stage shock-induced metamorphism of the St. Severin rather than a thermal origin of NRM. More than an order difference in NRM/ARM (anhysteretic remanent magnetization) and NRM/SIRM (saturation isothermal remanent magnetization) with respect to a terrestrial signal can be a manifestation of taenite conversion to tetrataenite.
