The Armorica ‘microplate’: fact or fiction? Critical review of the concept and contradictory palaeobiogeographical data
Abstract The problem of an ‘Armorica microplate’, detached from Gondwana and having had during part of the Palaeozoic an independent latitudinal evolution, is reconsidered in terms of a criticalExpand
Late Ordovician glaciation in southern Turkey
ABSTRACT We present a new survey of several Palaeozoic sections in both the Taurus range and the Border Folds that documents typical glacial features including a glacial pavement and striatedExpand
Alternative approach to the Variscan Belt in southwestern Europe: Preorogenic paleobiogeographical constraints
Most of the models proposed for the Variscan Belt of southwestern Europe have been based on structural, metamorphic, and magmatic data. An alternative approach is proposed here, based onExpand
Early Palaeozoic palaeobiogeography of the Variscan regions
Abstract The palaeobiogeographic method appears to be an attractive alternative for reconstruction of the palaeogeography of the Variscan regions during the Palaeozoic. The evolution of faunalExpand
The Ordoviciam, Silurian and Devonian sadimentary rocks of the Ossa-Morena Zone (SW Iberian Peninsula, Spain)
Se revisa el registro sedimentario del Ordovicico, Silurico y Devonico de la Zona de Ossa Morena del Macizo Hesperico (o Iberico), referido esencialmente a la parte espanola, pero complementado conExpand
Deciphering ``temperature'' and ``salinity'' from biogenic phosphates: the δ18O of coexisting fishes and mammals of the Middle Miocene sea of western France
Abstract This study examines the possibility of estimating the oxygen isotopic composition and temperature of seawater by using a combination of δ18O values of phosphate from coexisting fishes andExpand
The late Ordovician diamictic formations from southwestern Europe: North-Gondwana glaciomarine deposits
Abstract This paper presents a review and a discussion of the clast-bearing formations (diamicts) which occur in the uppermost part of the Ordovician succession of numerous regions in SouthwesternExpand
δ18O and REE contents of phosphatic brachiopods: a comparison between modern and lower Paleozoic populations
δ18O values of both carbonate (18.7–25.1‰) and phosphate (15.1–16.7‰) components of the francolite from the fossil brachiopod shells are interpreted as the result of a partial resetting of pristineExpand
Ordovician and Silurian stratigraphy and faunas (graptolites and conodonts) in the Ossa-Morena Zone of the SW Iberian Peninsula (Portugal and Spain)
30 paginas.-- In: Gutierrez-Marco, J.C. and Rabano, I. (eds.), Proceedings of the Sith International Graptolite Conference of the GWG (IPA) and the 1998 Field Meeting of the InternationalExpand
Terranes within the Iberian Massif: Correlations with West African Sequences
The Iberian Peninsula consists of two very different parts: (1) the eastern half which constitutes the westernmost extension of the Alpine orogen; and (2) the western half (Iberian Massif)Expand
