Description
Summary:Mt. Early and Sheridan Bluff (87°S) are the above ice expression of Earth’s southernmost volcanic field that lies approximately 300 km from the South Pole. The dataset supplies the locations and lithological descriptions of the units that the samples were collected from for dating and petrological study. Fundamental compositional information on the mafic volcanic rock samples include whole rock MgO concentrations (wt.%), the forsterite content of olivine and the oxygen isotopic composition of olivine. The dataset also provides a record of what samples have been analyzed for major and trace elements by XRF and ICP-MS, mineral chemistry by EMPA, radiogenic isotopes of Sr, Nd and Pb on whole rock powders by ICP-MS and dating by 40Ar/39Ar method.
