Geochemistry and significance of basaltic rocks dredged from the South Tasman Rise and adjacent seamounts

Basalts dredged from two seamounts separated by some 200 km and built on ca 50-35 Ma oceanic crust west of Tasmania have slightly LREE-depleted N-MORB affinities and were probably generated in a spreading ridge or near-ridge setting. They are compositionally very similar to 60 Ma basalts drilled at...
