The Blake Plateau ferromanganese samples were obtained during the USGS GOS74 Expedition in 1965. Most of them are related to a phosphorite substrate. Samples were ground and subsequently sieved to <105 micons. Water loss was determined after heating the powder at 500°C for one hour. Mn, Fe, P, Co, Cu, Mo, Ni are determined by ICP (Inductively Coupled Plasma) Spectroscopy after separation following a disgestion in HNO3-HCl-HF solution.
