  • The Proto-Andean Margin of Gondwana: an Introduction
    Downloaded from http://sp.lyellcollection.org/ by guest on September 29, 2021 The proto-Andean margin of Gondwana: an introduction R. J. PANKHURST 1 & C. W. RAPELA 2 1 British Antarctic Survey, c/o NERC Isotope Geosciences Laboratory, Kingsley Dunham Centre, Keyworth, Nottingham NG12 5GG, UK 2 Centro de Investigaciones Geol6gicas, Universidad Naeional de la Plata, 644 Calle No. 1, 1900 La Plata, Argentina Abstract: A basic background is presented for the discussion of the Early Palaeozoic geology of western Argentina covered by this book. This includes the definition and terminology of orogenic cycles on this part of the Gondwana margin, represented by the Eastern Sierras Pampeanas. The Pampean orogeny (Early Cambrian) relates to an intense but short-lived period of terrane collision predating the rifting of the Precordillera terrane from Laurentia. The Famatinian cycle is predominantly represented by intense subduction- related magmatism of Early-Middle Ordovician age, developed on the continental margin of Gondwana during the rifting and drifting of the Precordillera terrane. The Grenvillian basement of the latter is further exemplified by a new Rb-Sr whole-rock isochron age of 1021 + 12Ma for orthogneisses from the Western Sierras Pampeanas. A mid-Ordovician granite in this area (dated at 481 4-6 Ma by U-Pb ion microprobe data) may be related to rifting while the Precordillera terrane was still attached to Laurentia. A divergence of opinion is pointed out between some authors in this book who favour mid-Ordovician collision of the Precordillera with Gondwana, and others who place it much latter, in Silurian or Devonian times.

Ramos Abstract During the late Neoproterozoic and Paleozoic times, the Southern Andes of Argentina and Chile (21º-55º S) formed part of the southwestern margin of Gondwana. During this period of time, a set of continental fragments of variable extent and allochtony was successively accreted to that margin, resulting in six Paleozoic orogenies of different temporal and spatial extension: Pampean (Ediacaran-early Cambrian), Famatinian (Middle Ordovician-Silurian), Ocloyic (Middle Ordovician-Devonian), Chanic (Middle Devonian-early Carboniferous), Gondwanan (Middle Devonian-middle Permian) and Tabarin (late Permian-Triassic). All these orogenies culminate with collisional events, with the exception of the Tabarin and a part of the Gondwanan orogenies that are subduction-related. Keywords Paleozoic, Southern Andes, Pampean orogen, Ocloyic orogen, Famatinian orogen, Chanic orogen, Gondwanan orogen, Tabarin orogen. 133 134 1 Introduction In the southern part of the Andean Cordillera (21º-55º S, Fig. 1A) and nearby areas, there are Neoproterozoic (Ediacaran)-Paleozoic basement relicts of variable extension. This basement has been involved in orogenic events prior to the Andean orogeny, which is related to the current configuration of the Andean chain (active since the Cretaceous).
