TL;DR: In this paper, the extent and nature of the Archaean-Palaeoproterozoic craton of Rio de la Plata of southern South America, a major but poorly understood crustal component in NeoproTERozoic plate reconstructions, as well as the depositional, metamorphic and magmatic history of the surrounding orogenic belts, are reviewed and reassessed, in part through the analysis of material recovered from deep boreholes in western Argentina that penetrated Palaeozoic cover into basement.

TL;DR: A detailed study of the pre-Silurian geology of the Sierras de Cordoba, Eastern Sierra Pampeanas, is used to define the sequence of magmatic and metamorphic events during the Pampean orogeny.

TL;DR: In this paper, a detailed study of a 500 km transect in the Sierras Pampeanas, central-west Argentina, two pre-Silurian tectono-magmatic episodes are recognized and defined, each culminating in micro-continental collisions against the proto-Andean margin of Gondwana.

TL;DR: The results of 64 new KAr age determinations, together with 32 previously published ages, show that after a period of erosion of the basal complex, Miocene volcanic activity started around 20 Ma in Fuerteventura and 15 Ma in Lanzarote, forming a tabular succession of basaltic lavas and pyroclastics with a few salic dykes and plugs as discussed by the authors.

TL;DR: The role of the Rio de la Plata craton of South America in the light of new evidence from a borehole at the eastern end of the Tandilia belt (38°S) is reviewed in this article.
