PROJECT DESCRIPTION

The Grønfjorden Bed represents the earliest Paleogene sedimentary deposits in the
Central Tertiary Basin on Spitsbergen. It has a patchy distribution, and consists of conglomerates and sandstones of fluvial origin that rest unconformably upon Lower Cretaceous strata. It has received limited emphasis in research due to the attention received by the productive coal seams higher up in the stratigraphy. This study has investigated the Grønfjorden Bed and associated sedimentary deposits in detail through the use of conventional sedimentary logging and remote photography and photogrammetric modelling. The photogrammetric models have provided virtual outcrops o which detailed sedimentological analysis has been performed. On the basis of detailed facies analysis, three different, though closely related facies associations were distinguished.
