By contrast, in the Goa schist belt (GSB), phyllites/schists (unmixed ages - 2436 ¡À 34, 2543 ¡À 66 and 2625 ¡À 36 Ma) and polymict conglomerates (unmixed ages - 2458 ¡À 34 and 2566 ¡À 53 Ma) possess two generations of tectonic fabrics and are the youngest dated metamorphic unit in the WDC. The deformed Quepem granitoid pluton located along the axial zone of the regional-scale N-trending gently plunging upright folds in GSB yields comparable chemical age (2565 ¡À 33 Ma). Angular to sub-rounded and boulder to granule sized polymict clasts of Peninsular gneisses (3128 ¡À 60 Ma), foliated granitoids, amphibolites, BIFs and low-grade quartzite/chlorite-muscovite schists in GSB para-conglomerates suggest the sediments deposited in shallow basin were derived from neighboring sources, e.g. the Peninsular gneisses and SSB supracrustals. The Neoarchean deformation-metamorphism marks the closure of the Goa basin synchronous with the 2.4-2.6 Ga accretion of the West and the East Dharwar Cratons.
Based on the results of this study, the following correlation among Mesoarchean-Neoarchean crystallites in the Western Dharwar Craton and the Antongil-Masora Block, NE Madagascar (in italics below) appears realistic, e.g. 2.4-2.6 Ga Goa schist belt ¡Ö Mananara Group; 2.5 Ga Quepem granitoid ¡Ö Masoala Suite; 3.1 Ga Shimoga schist belt ¡Ö Fenerivo Group; 3.1 Ga Peninsular gneiss suite ¡Ö Nosy Boraha suite.
