We report the discovery of a large accumulation of micrometeorites in a supraglacial moraine at Larkman Nunatak in the Grosvenor Mountains of the Transantarctic Range in Antarctica. The micrometeorites are present in abundances of ~600 particles Kg-1 of moraine sediment and include a near complete c...
