Abstract
Mt. Takahe is unusual among Marie Byrd Land volcanoes for its geochemical anomalies. These include the lowest 143Nd/144Nd ratios in West Antarctica, and unusually high but unpredictable Ba values. These anomalies are believed to originate in a pre-85Â Ma subduction mélange at the base of the lithosphere, which seems to be the source of Mt. Takahe basaltic rocks.
