The 135 Ma Paraná-Etendeka Large Igneous Province (PELIP) is one of the largest areas continental flood basalt (CFB) volcanism in world and widely agreed to be a product intracontinental melts related thermal anomalies from Tristan mantle plume. province rifted during break-up Gondwana, as plume transitioned into an oceanic geodynamic environment. This study reports analyses plume-derived basal...

Chondrites are sediments of materials left over from the earliest stage solar system history. Based on their undifferentiated nature and less fractionated chemical compositions, chondrites widely considered to represent unprocessed building blocks terrestrial planets embryos. Models composition generally find chondritic relative abundances refractory lithophile elements (RLE) in bulk bodies ("c...

Eighteen samples from the south-western part of Ronda lherzolitic massif have been analysed with bulk-rock and in-situ techniques to unravel fate Cu, platinum-group element chalcogens (S, Se) in a middle Proterozoic subcontinental lithospheric mantle segment variably overprinted by kilometre-scale porous flow percolation asthenosphere-derived silicate melts during Alpine orogeny. Chalcogen elem...

This paper describes unusual graphite–sulfide deposits in ultramafic rocks from the Serranı́a de Ronda (Spain) and Beni Bousera (Morocco). These deposits occur as veins, stockworks and irregular masses, ranging in size from some centimeters to a few meters in thickness. The primary mineral assemblage mainly consists of Fe–Ni–Cu sulfides (pyrrhotite, pentlandite, chalcopyrite and cubanite), graph...
