    Abstract

    The deep crustal structures of Warakuma LIP have been imaged using combined-gravity-seismic methods even with absence of the thermal system with younger LIPs. Hence, this work adds to the body of knowledge regarding geophysical imaging of the lower-crustal signature of the magmatic processes in ancient LIPs. Modelling results indicate an extensive area with very thick crust (> 45) and high-density materials (> 2.85 g/cm3) at the base of the crust, interpreted as a magmatic underplate. This area occurs beneath the western Musgrave Province and extends to the north-west and north-east, consistent with being part of the Warakuma LIP.
