dc.description.abstractMicrotektites belonging to the Australasian tektite strewn field are found in the substrate of a ferromanganese crust dredged from the Central Indian Basin. They are identified on their physical appearance, geographic occurrence and chemical composition. The ferromanganese crust has a thickness range of 6-17 mm, and its chemistry and mineralogy indicate hydrogenic accretion. Because the Australasian strewn field has an age of approximately 0.77 Ma, this finding implies that the overlying Fe-Mn crust has minimum accretion rates of 7.8-22.1 mm/Myr, which are much higher than the average growth rates of hydrogenic crusts
