Franklinian Composite Tectono-Sedimentary Element, North Greenland

Abstract

The Franklinian Composite Tectono-Sedimentary Element (CTSE) in North Greenland is dominated by Neoproterozoic–lowermost Devonian sedimentary strata and includes early synrift through to passive-margin TSEs of mixed carbonate and siliciclastic facies. The sedimentary successions are well exposed in much of northern Greenland, but in parts were strongly affected by the Ellesmerian Orogeny, resulting in a fold and thrust belt that deformed the northernmost exposures. An exposed palaeo-oilfield attests to the petroleum potential of the basin. Several formations have good source potential and several others have good reservoir properties. Palaeoheat-flow indicators show that temperatures increase to the north, where much of the basin is over-mature. Because of the remoteness of the area and the restricted locations where there is likely to remain petroleum potential, the basin is not currently a target for exploration.
