Mineralogy and geochemistry of a basalt from ODP Hole 119-738C
The Lower Cretaceous tholeiitic basalt cored at Site 738, on the southernmost part of the Kerguelen Plateau, shows anomalous Sr, Nd, and Pb isotopic compositions compared to other lavas from Kerguelen Island and the Kerguelen Plateau. The strongly negative value of eNd (– 8.5) and high 207Pb/204Pb r...
