Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Conodont biostratigraphic research on the Comabella Formation at Villech (Spanish Central Pyrenees), a 54 m thick pinkish-greyish compact hemipelagic limestone section situated in the Compte "subfacies area", reveals an Eifelian to early Frasnian age for the studied interval. The base of the Formation is of lower Eifelian age (costatus Zone), indicated by the lowest local record of Polygnathus angustipennatus, associated with P. partitus. The kockelianus and eiflius zones are recognized in the lower half of the section. The uppermost Eifelian and lowermost Givetian (ensensis and hemiansatus zones, respectively) have not been found so far but might be located in a covered interval. Other biozones recognized in the section are the timorensis-rhenanus/varcus, ansatus, semialternans, hermanni, disparilis and norrisi zones in the Givetian, all indicated by their respective index species and the MN1 Zone (occurrence of Ad. binodosa and Ad. pristina) in the Frasnian. A black shale and limestone layer in the upper part of the Villech section could represent the local signature of the upper part of the global Taghanic Crisis.
