The composition of the impurities contained in Antarctic snow has yet to be established. This work is based primarily on the study of geographical variations and on the establishment of a fallout table, backed up by some observations as to the identification of the various possible origins. Analysis by atomic absorption spectrometry of the elements sodium, magnesium, calcium, potassium and iron is performed as well as analysis by neutron activation of the elements chlorine, sodium, and manganese. Sampling procedures and sample preparation, as well as analytical techniques, are discussed. Draft trans. of Centre National de la Reccherche Scientifique, Grenoble. Laboratoire de Claciologie.
