A new discrimination scheme for oceanic ferromanganese deposits using high field strength and rare earth elements

Ternary diagram presenting the classification scheme and delimited areas for each genetic process involved in the formation of oceanic ferromanganese mineralizations using HFSE and REE data. The dotted arrows present the mixing trends between two genetic processes highlighting the continuum existing between hydrogenetic-hydrothermal crusts and hydrogenetic-diagenetic nodules. Solid arrows show evolution trends of a sample set related to only one genetic process without influence of another one.74
