More purely marine features reworking the coarse fraction of deltaic deposits are the cheniers or successive beach ridges of south-western Louisiana (Byrne et al., 1959). They form beautiful birdfoot complexes in the Rhone delta, where they have been mapped by C. Kruit. Every kind of transition exists between digitated deltas such as the Mississippi and stunted deltas such as the Guadalaviar mouth near Valencia in Spain (see Gulliver's classification, 1898-1899). Climatic conditions diversify the processes in deltaic sedimejitation. One of the most curious climatic types is the arctic or periglacial delta, principally represented in Siberia (Lena, Yana, Indigirka, Kolyma), and existing also in Canada (Mackenzie). The deposits are deeply frozen during the greater part of
