Iron and manganese diagenesis in deep sea volcanogenic sediments and the origins of pore water colloids

Abstract:

Volcanogenic sediments are typically rich in Fe and Mn-bearing minerals that undergo substantial alteration during early marine diagenesis, however their impact on the global biogeochemical cycling of Fe and Mn has not been widely addressed. This study compares the near surface (0-20cm below sea floor [cmbsf]) aqueous (<0.02μm) and aqueous+colloidal here in after 'dissolved' (<0.2μm) pore water Fe and Mn distributions, and ancillary O 2(aq), NO3- and solid-phase ...
