Meteorite finds by EUROMET near Frontier Mountain, North Victoria Land, Antarctica

Abstract

Abstract— A team from EUROMET (a joint initiative of scientific institutions in Europe interested in meteorites) was sent for the first time to Antarctica in the 1990/91 season to undertake a systematic search for meteorites. The project was organised within the framework of the Italian Antarctic Program (Programma Nationale di Richerche in Antartide, PNRA). The search was carried out in the vicinity of Frontier Mountain (North Victoria Land) and 256 meteorite fragments were discovered, most of which were wind‐blown across the blue‐ice field to the NE of Frontier Mountain and finally caught in an ice depression about 5 km to the N. The larger meteorites which remained on the ice surface from which they were uncovered may have been transported down to the mountain edge where they have subsequently been destroyed or covered in debris. A search for meteorites at neighbouring Sequence Hills, where similar glaciological conditions as at Frontier Mountain exist, proved unsuccessful. At this location the surface of the blue ice in the valleys with suspected meteorite concentrations was covered by meltwater lakes.
