Abstract

Ferrimagnetic Cr-Fe and Mn-Fe spinels are the dominant remanence carrying phases in the late Triassic Lunde Formation. These have largely been identified by magnetic mineral extraction from the sediments, combined with microscopy. The extensive removal of most of the originally deposited magnetic Fe-Ti oxides during diagenesis has left the Cr-Fe and Mn-Fe spinels as a mineral residue which is resistant to dissolution. The rock magnetic signature of these minerals is not sufficiently known, to be able to identify these minerals on the basis of their magnetic properties alone.
