@@@@Highlights •Ultramafic-mafic cumulate sequence from Goa represents dismembered SSZ oceanic crust.•Depleted to enriched melt composition reflects mantle heterogeneity.•Paleo-ocean closure and arc accretion culminated to GDC formation.•2.6–2.5 Ga age coincides with Neoarchean global subduction-accretion event.
