[PDF][PDF] Iberian Ordovician and its international correlation

JC Gutiérrez-Marco, AA Sá, I Rábano, GN Sarmiento… - Stratigraphy, 2015 - academia.edu
The regional chronostratigraphy of the British Ordovician, established mainly for shelly
facies, is hard to correlate in the Iberian Peninsula, especially after the separation and drift of
Avalonia from Gondwana by the early Middle Ordovician. The same applies to the
Ordovician global scale, whose stratotypes involve deeper-water facies and faunas not
recorded in the high-paleolatitudinal settings of southern peri-Gondwana. In order to solve
the problem, an alternative regional scheme for the “Mediterranean” Ordovician was …
