Ferro-manganese oxide growth on shark teeth from cenral Indian Ocean basin
Abstract
Study of ferro-manganese oxide growth on apatitic substrates like shark teeth enamel from siliceous sediment environment (lat. 10 degrees S and long. 75 degrees E) suggests the changes in depositional environments within the sediment layer through the growth history of these oxides. Though the nature of substrates does not have any control over the mineralogy and chemistry of Fe-Mn oxides, an active sink like loose sediment or altered basaltic coat appears to be the primary requirement before ferric hydroxide coat on hard nucleating agent
