Palaeoenvironmental implications derived from a piston core from east lobe Bonney, Taylor Valley, Antarctica
Abstract A 270 cm long sediment sequence was recovered with a piston corer from east lobe Bonney, Taylor Valley, Antarctica, and characterized according to its sedimentological, mineralogical, and geochemical properties. It is the first record of such length recovered from east lobe Bonney. The sedi...
