The Tectonics of the Patagonian Basins Special Issue is dedicated to the latest achievements related to the Patagonian Basins and their tectonic evolution. This Special Issue includes 24 chapters which individually analyze in chronological order the events that characterized the evolution of the Patagonian Basins and Antarctic Peninsula, starting with i) the processes associated with Paleozoic to Triassic basins in Patagonia, ii) the initial stages of Patagonian Basin subsidence in Late Triassic to Early Jurassic times, coetaneous with the southeastern Pangea instability at the time of progressive roll back of the subducted Pacific Ocean floor, followed by iii) a series of Jurassic within-plate contractional episodes that temporarily interrupted sag and synrift stages, iv) renewed synrift and sag extension in Early Cretaceous times, v) the closure of the Neuquén, Malvinas and Austral basins in Late Cretaceous times in a context of the shallowing of the subducted Farallón Plate, vi) Paleogene basin development associated with dynamic subsidence in a context of renewed roll back of the subducted Pacific plates, and finally vii) the inception of Neogene foreland basins.
