The Origin and Significance of Antarctic Meteorites

Abstract More than 25,000 meteorite specimens have been recovered from Antarctica since systematic collection programs began in the mid 1970's. When properly recovered and curated, these specimens serve as a uniquely representative sample of the extraterrestrial material accreting to our planet, providing our best glimpse of the full lithological and geochemical breadth of the inner solar system. Antarctic meteorite concentrations are intimately linked to variations in climate and ice sheet behavior over the past several million years, with each individual icefield exhibiting distinct and often unique characteristics.
