The sedimentary environment of the Argentine Basin is largely controlled by powerful current systems and intense gravitational mass transport (Ledbetter and Klaus 1987). Sinking particles, or particles already deposited, are subjected to a lateral drift over wide passages, or become resuspended (compare with Section 12.3.2). This...

Fig. 6.17 Typical nitrate concentration profiles of surface sediments from different productivity regions in the South Atlantic Ocean. The profiles from the continental slope of the Argentine and the Cape Basin indicate denitrification at about 3 cm. The profile from an oligo-trophic equatorial site shows no denitrification.

This is present in Antarctica, the southern two-thirds of South America (Parana Basin, Sierras Australes and the provinces of Salta and Jujuy in Argentina, Bolivia and southern Peru central and northern Peru, as well as Ecuador and western Colombia are very poorly known in Devonian terms), the Falkland Islands, South Africa, Ghana, and Guinea (Racheboeuf and Villeneuve, 1992). In the Argentine Precordillera (Herrera and Racheboeuf, 1997), as in the Silurian, there is evidence for boundary mixing between the Malvinokaffric Realm, plus the Old World and Eastern Americas realms, as is also the case in northern Chile (Boucot etal., 1995).
