TL;DR: In this article, the authors used secondary electron (SEM) and cathodoluminescence (CL) imaging to date zircon and monazite from granulite-to amphibolite-facies rocks of the Vosges mountains (central Variscan Belt, eastern France) by ion-microprobe and conventional U-Pb techniques.

TL;DR: New SHRIMP U-Pb zircon, Rb-Sr whole-rock, and 40Ar-39Ar data are presented for the Jurassic silicic volcanic rocks and related granitoids of Patagonia and the Antarctic Peninsula as discussed by the authors.

TL;DR: A review of the post-Cambrian igneous, structural and metamorphic history of Patagonia, largely revealed by a five-year programme of U-Pb zircon dating (32 samples), geochemical and isotope analysis, results in a new Late Palaeozoic collision model as the probable cause of the Gondwanide fold belts of South America and South Africa.

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.
