Detrital zircon U–Pb ages are used to provide constraints on the geologic evolution of the sediment source area(s) north of the Sverdrup Basin from the middle Permian to Late Triassic. Previous research on facies relationships and sediment prograda

The objective of venoplasty is to improve venous return from the CNS, yet no flow data were presented in the Traboulsee et al.1 article examining the safety and efficacy of venoplasty in MS. The venoplasty trial by Zamboni et al.2 showed that only 54

The Late Triassic was the time of the Early Cimmerian and Indosinian orogenies that closed the Paleotethys Ocean, which occurred earlier in the Alpine-Carpathian-Mediterranean area, later in the Eastern Europe-Central Asia and latest in the South-Eas

This study summarizes the results of petrographic and geochemical analysis of Middle Triassic strata from the Sverdrup Basin in the Canadian Arctic. In this work, we investigate the distribution and depositional conditions of dispersed organic matter

The Lower Cretaceous Isachsen Formation is a widespread, siliciclastic succession up to 1.4 km thick that records the northwestward progradation of fluvio-deltaic environments into the Sverdrup Basin in the Canadian Arctic. Although the Isachsen Form

Sequence stratigraphy is a stratigraphic discipline in which the defined stratigraphic surfaces represent either breaks in deposition or changes in depositional trend. Two approaches for defining sequence stratigraphic surfaces and units have evolved

Middle to Upper Devonian strata of the Franklinian Basin in the Canadian Arctic contain a rich record of Phanerozoic tectonic events along the northern margin of Laurentia. We report detrital thermochronometric zircon (U–Th)/He ages (ZHe; number of

Jurassic to Cretaceous strata of Sverdrup Basin contain both marine and nonmarine fossils that serve to date interlayered sandstone and mudstone units and interpret paleoenvironments and paleoclimates. Applying a multi-variate statistical approach to
