| contents | Global Series and Stages for the Ordovician System: A Progress Report S. Finney Ciencias de la Tierra Argentin Ordovician Precordillera Chronostratigraphy There is no global standard set of chronostratigraphic/geochronologic subdivisions for the OrdovicianSystem/Period. British series/epochs are often used as de facto nomenclature on stratigraphic correlation chartsand geologic time scales. However, they were not widely adopted outside of the British Isles because the highdegree of biogeographic provincialism and ecologic differentiation of Ordovician faunas prevent the Britishseries from being correlated with precision and high resolution. As a result, several independent and very differentregional sets of series and constituent stages were established for the Ordovician System with each generallyapplicable to a different paleoplate or modern continent. Of course, this has greatly confused Ordovicianchronostratigraphy/geochronology and often results in imprecise correlations of Ordovician stratigraphic successions.An example is the Argentine Precordillera where British series are traditionally used to correlateOrdovician strata that contain faunas of predominately Laurentian affinity. The Subcommission on OrdovicianStratigraphy of the International Commission on Stratigraphy is addressing this problem by developing a standardset of Global Series and Stages for the Ordovician System. The Subcommission has made considerableprogress, but it must complete its work expeditiously. The new global standard will facilitate reliable global correlation.It will provide a common language for discussing Ordovician strata, fossils, and geologic events. Itwill be of fundamental importance in advancing research on Ordovician rocks worldwide. 2005 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50530402 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.4 Vol.3 |
