Figure F23. (A) Manganese and (B) iron concentrations at Site 1212 decrease significantly through lithologic Unit I (0.00-53.60 mbsf) and remain relatively uniform through the underlying sediment column. As at previous sites, there is an excursion in the manganese profile at the unconformity in Core 198-1212A-7H, implying the presence of Mn-rich minerals. Low sample volume at 141.6 mbsf precluded a complete suite of analyses.
