Whole rock and mineral geochemistry of samples from Mount Waesche, Marie Byrd Land, Antarctica
Abstract:
Ages of lava flows between 426 and 96 ka from Mount Waesche, a stratovolcano in the Executive Committee Range of Marie Byrd Land, West Antarctica, indicate greater eruption frequency during interglacial periods, suggesting the glacial overburden influences the magmatic plumbing system. We conducted a geochemical and petrologic study on lavas that erupted in the last peak interglacial period (ca. 100-130 ka), and lavas that erupted in the preceding glacial period (ca. 138.7-150.5 ka) to evaluate changes to the magmatic system as a function of the ice load. This dataset contains mineral chemistry and whole rock geochemical data.
