Geochemical data from basalts, basaltic andesites, and andesites of the Mesozoic-Cenozoic (143-44 Ma) from Livingston, Greenwich, Robert, King George, and Ardley Islands of the South Shetland archipelago, Antarctica, are presented. The rocks have variable SiO2 Of approximately 46-61 wt%, Al2O3 of 15...
