A multi-proxy provenance study of Late Carboniferous to Middle Jurassic sandstones from the eastern Sverdrup Basin was undertaken employing optical petrography and heavy mineral analysis, chemical analysis of apatite, garnet and rutile grains, as wel

Mixed local and ultra-distal volcanic ash deposition within the Upper Cretaceous Kanguk Formation, Sverdrup Basin, Canadian Arctic Islands

Autor: Simon Schneider, Peter Hülse, Michael J. Flowerdew, Martin J. Whitehouse, Michael A. Pointon

Publikováno v: Geological Magazine. 156:2067-2084

The Upper Cretaceous Kanguk Formation of the Sverdrup Basin, Canadian Arctic Islands, contains numerous diagenetically altered volcanic ash layers (bentonites). Eleven bentonites were sampled from an outcrop section on Ellesmere Island for U–Pb zir

Tracking compositional changes within the High Arctic Large Igneous Province using zircon Hf isotopes from altered volcanic ash layers of the Sverdrup Basin, Canada

Autor: Peter Hülse, Simon Schneider, Ian L. Millar, Michael J. Flowerdew, Michael A. Pointon, Martin J. Whitehouse

During Late Cretaceous times the Sverdrup Basin, Arctic Canada, received considerable air-fall volcanic material. This is manifested as numerous centimetre- to decimetre-thick diagenetically altered volcanic ash layers (bentonites) that occur interbe

Fault activity and diapirism in the Mississippian to Late Cretaceous Sverdrup Basin: New insights into the tectonic evolution of the Canadian Arctic

Autor: Berta Lopez-Mir, Peter Hülse, Simon Schneider

Publikováno v: Journal of Geodynamics. 118:55-65

The opening and pre-opening history of the Amerasia Basin is poorly constrained. Key tectonic events have been interpreted from outcrop data in adjacent sedimentary basins or from geophysical data along its continental margins. However, due to its lo

A new Early Jurassic gastropod from Ellesmere Island, Canadian Arctic - an ancient example of holoplanktonic gastropods

Autor: Alexander Nützel, Reinhart Veit, Peter Hülse, Simon R. A. Kelly, Laura Tilley, Simon Schneider

Publikováno v: Bulletin of Geosciences. :229-242

A new, most probably holoplanktonic gastropod genus and species, Freboldia fluitans Nutzel & Schneider, is reported from the Early Jurassic (Pliensbachian) of Ellesmere Island, Canadian Arctic. Its shell is very thin, small, with a maximum diameter o

Macrofauna and biostratigraphy of the Rollrock Section, northern Ellesmere Island, Canadian Arctic Islands – a comprehensive high latitude archive of the Jurassic–Cretaceous transition

Autor: Berta Lopez-Mir, Peter Hülse, Simon Schneider, David W. Jolley, Simon R. A. Kelly, Jörg Mutterlose, Jens O. Herrle, Claudia J. Schröder-Adams

Publikováno v: Cretaceous Research. 114:104508

The Rollrock Section in the Sverdrup Basin of Arctic Canada is one of the northernmost outcrops where the Jurassic-Cretaceous transition is accessible. The over 500 m thick sedimentary succession exposes the Oxfordian to Valanginian Ringnes and Deer
