dc.description.abstract Nuclei of ferromanganses nodules from the Central Indian Ocean Basin show the presence of abundant plagioclase feldspars (1-3 mm diameter). They are indentified as calcic plagioclase (peak at 3.20 A). Plagioclase chemical composition (CaO 6.4-20.5%) shows a range of An 44-90%. The mineral chemistry, together with the bulk composition of the host nuclei, indicate that they are of bassaltic composition. A possible source could be the numerous seamounts in this basinal area
