one modern ocean basin were examined for marcasite (Table 1). Although only a subset of these is described in some detail here, marcasite occurs in all units (Table 1). Whereas in some samples marcasite had undergone partial pyrite inversion, in the majority of samples marcasite domains were large enough to be identified with an optical microscope.
