Abstract
This brief communication describes the first finding of glauconite sand alternating with calcareous foraminiferal–coccolithic ooze on the Piedra Buena contourite terrace of the Patagonian continental slope at a depth of 2327 m. It is suggested that the fine-sand glauconite grains were supplied from the shelf during glaciations, rewashed and sorted by alongslope (contour) currents of the Circumpolar Antarctic waters with the formation of sandy glauconite contourites.
