Neoproterozoic glacial and associated facies in the Varanger (ex-type) area

Purpose: The trip, part of the IGCP 512 "Neoproterozoic Ice Ages" project, will examine glacial (sensu-lato) deposits and associated carbonate units relevant to ongoing discussions on the extent, causes and correlations of late Neoproterozoic glaciations. Both lower (Smalfjord Formation) and upper (Mortensnes Formation) glacial, glaciomarine and fluvioglacial deposits, respectively likely Marinoan and Gaskiers equivalents, will be studied in the Laksefjordvidda-Tanafjord-Varangerfjord area. Sections through dolostones tentatively correlated with the 'Bitter Springs' anomaly (Båtsfjord Formation) will be examined. Facies variations in the Smalfjord Formation cap-dolostone (Marinoan type, lower Nyborg Formation) due to variable clastic influences will be seen. The glacial striations at the base of the Smalfjord Formation at Oaibaccanjar'ga (Bigganjar'ga) are included in the excursion.

A few parts of the trip may be arduous, with some cross-country walks and long boat rides.

Participants must be fully prepared for possible wet, windy and cold fieldwork weather. The average daytime temperature in August is around 10°C, but will likely go below zero at night time. For the boat rides, it is very strongly suggested that participants bring waterproof leggings. Life-vests will be provided.
