Abstract

During the recent years more than 5000 meteorites have been collected in the Antarctic. They are mainly found on the surface of blue ice fields close to the Allan Hills and the Yamato Mountains. Taking into account all available analytical data of these meteorites and considering observations in the field the large number of meteorites found at the Allan Hills site can be explained by several specific circumstances:

  1. (1)

    On the bare ice fields in Antarctica meteorites with diameter less than 1 cm are easily detected.

  2. (2)

    The weathering of meteorites under the climatic conditions of Antarctica is very small. Therefore, higher densities of meteorites can build up on the surface of ice fields with no snow accumulation.

  3. (3)

    Concentration mechanisms due to ice movement and ablation of the ice are active. However, for the Allan Hills sampling site the collection of meteorites fallen on much larger areas is of less importance.
