    Abstract: The Northwest Atlantic Mid-Ocean Canyon is a depositional–erosional linear feature which extends southward from the northern Labrador Sea to the Sohm Abyssal Plain. Analysis of the data accumulated over the past 20 yr allows us to conclude: (1) The canyon does not have any major tributaries; (2) it is Quaternary in age; and (3) it is not a tectonic feature. However, neither the source nor the sedimentary process which constructed the canyon can as yet be established.

    Abstract: Clay sediments off-shore from the Antarctic Continent. The clays were studied in samples of marine sediments collected from fifty points off-shore in the Antarctic between 60° and 150° Longitude West Two types of sediment are found in this region : near the coasts, there are grey muds of a detrital nature, rich in quartz (about 15%) and in plagioclase (about 15%) ; further away from the coast, there are diatomaceous muds, consisting chiefly of the shells of these algae, but in which small amounts of clay are also found, The clay minerals of the grey muds are illite (about 15%), montmorillonite (about 20%), and chlorite (about 20%) ; the remainder of the clay fraction consists of less well defined minerals of the septochlorite type and perhaps kaolinite. These same minerals are also found in the diatomite muds, in which montmorillonite is always somewhat more abundant. The presence of montmorillonite in this region is surprising and tits possible origin is discussed.
