Abstract: Hydrogenetic cobalt-rich ferromanganese crusts (cobalt-rich crusts, CRCs) are expected as potential mineral deposits for rare earth elements and platinum group elements as well as cobalt, nickel, and manganese (Manheim 1986; Rona 2003). Previous investigations have… read more here.

DOI: 10.1016/j.rgg.2018.03.001
Abstract: Abstract Variations in mercury contents in marine sediments have implications for hydrothermal activity, paleoclimate, depositional environments, and primary bioproduction. Mercury contents reach 148 ppb in hydrogenic ferromanganese crusts on flat-topped seamounts. Such crusts, with up… read more here.

DOI: 10.1038/s41598-017-17077-8
Abstract: Deep-sea hydrogenetic ferromanganese crusts are both potential polymetallic resources and records of long-term environmental changes. For palaeoceanographic studies, it is important to construct a detailed and reliable chronological framework. Here, we report the results of… read more here.
