“…At Site U1471, the upper 10 mbsf are affected by currents that cause the advection of bottom waters through the upper portion of the sediments (Kramer et al, 2000;Swart, 2000;Moore and Swart, 2022). The almost complete dissolution of magnetite in the upper 2 mbsf and the subsequent growth of greigite from an SP size to an SD size with a measurable signal, as found at 3.06 mbsf, indicates that at some point between these two events Fe 2+ was available to be transported by diffusion and/or advection of the interstitial water and recrystallize in a different stratum.…”
