The Singhbhum craton records multiple stages of Precambrian dyke swarm emplacements, and several petrogenetic models have been proposed for their formation. We document elemental and Sr-Nd isotopic data for three major dyke swarms in the southern part of the craton, including the ca. 2.7 Ga Ghatgaon dyke swarm, the Early Proterozoic Keonjhar dyke swarm and the ca. 1.76 Ga Pipilia dyke swarm. The dykes exhibit basalt and basaltic andesite with minor andesite compositions, and also show trace element signatures typical of continental crustal rocks. Substantial variations can be observed in the age-corrected Nd isotopic data for Ghatgaon (εNdt = -4.8 to +4.6), Keonjhar (εNdt = -11.9 to +3.8), and Pipilia (a single sample with εNdt = -8.85) samples. The ambient mantle-like melting regime is inferred by the lack of magma compositions that could indicate elevated mantle potential temperature. The REE systematics of the samples indicates melting regimes can be constrained between spinel-stable depths and the spinel-garnet transition zone. Ubiquitous continental crust-like trace element and isotopic signatures are best explained by a mantle source with recycled crustal components, probably in the form of pyroxenites. The new Nd isotopic data argue against any simple secular evolution of the mantle source invoked in previous studies. Our data point out that the crustal recycling in the Singhbhum craton was likely an episodic phenomenon rather than a discrete, single-stage process since the Archean. Geochemical modelling indicates, trace element variations of Ghatgaon, Keonjhar and Pipilia dyke swarms are best explained by a sub-lithospheric mantle source with recycled crustal components (10% or less).
