Selected FORC diagrams for the three sample types in Hole C0008A. Note the presence of magnetite (a, b, d) for the types 1 and 2 samples and a mixture of both iron oxides and sulfides for a type 1 sample located at the boundary with type 3 (c) and the presence of pyrrhotite (i) and greigite (e, f, g, h) for the type 3 samples. B c is the coercivity field, B u is the interacting field between particles. SF is the smoothing factor
