Ferromanganese oxides on sharks' teeth from Central Indian Ocean Basin
Abstract
The mineralogy, composition and growth rates of ferromanganese (Fe-Mn) oxides over the sharks' teeth from the Central Indian Ocean Basin are presented. The trends of metal enrichment (Mn, Ni, Cu and Zn) and depletion (Fe and Co), the Mn/Fe ratio and the growth rates, basically indicate a hydrogenous source; in contrast, limited role of diagenesis. Furthermore, the nucleus does not seem to significantly affect the nature and bulk chemistry of the Fe-Mn oxides.
