Stratigraphy and depositional evolution of the Upper Palaeozoic sedimentary succession in eastern Peary Land, North Greenland

Abstract

The Upper Palaeozoic Foldedal and Kim Fjelde formations in eastern Peary Land are redefined on the basis of new biostratigraphic data, including fusulinids, conodonts, palynomorps and small foraminifera. The Foldedal Formation in its new definition includes all late Moscovian to Gzelian deposits in the region. It is separated by a major hiatus from the redefined Kim Fjelde Formation which includes mid-Permian (late Artinskian - Kungurian) carbonates and chert deposits. The Upper Carboniferous succession is dominated by cyclically interbedded siliciclastics and carbonates with minor tabular build-ups. The mid and Upper Permian succession consists of cool-water carbonates, spiculitic chert and shales.
