A Lower Carboniferous microflora from the Ørslev No. 1 borehole, island of Falster, Denmark

Abstract

A miospore assemblage composing 80 species is recorded from Lower Carboniferous strata in the Ørslev No. 1 borehole, island of Falster, Denmark. 45 spore types are referred to known species and 6 are proposed as new. The remaining forms are described with open nomenclature.The present knowledge of the Lower Carboniferous microfloras and their distribution within NW. Europe is briefly summarized. It is shown, that the Ørslev assemblage has a composition very close to that of the Lycospora pusilla (Pu) Zone assemblages from Scotland and northern England. Outside NW. Europe it shows affinities to spore assemblages described from eastern Canada and the south-west areas of the Soviet Union. The stratigraphical implications of these correlations are discussed. By means of indirect correlations the spore containing beds are referred to the Belgian Upper Tournaisian or Lower Viséan.
