North Gondwanan Emsian events

Abstract

On the basis of lithostratigraphic and biostratigraphic characteristics three Emsian events, first noted in the Czech Republic, have been distinguished in the north Gondwana regions of Spain and adjoining areas. These events, the Basal Zlichov Event (BZE), the Upper Zlichov Event (UZE) and the Daleje-Cancellata Event (DCE) are keystones in the Emsian stratigraphy in that they allow to deal with problems of stage and substage definition from a different all-embracing approach.
