Excursion Route and Road Log
The order of the days given is arbitrary, since weather-dependent boat journeys are included; these should be done at the earliest possible moment.
The use of hammers anywhere is strongly discouraged unless samples are being taken as part of a proper scientific study or from an outcrop where the material taken is present in great abundance. At Oaibaccannjar’ga, the use of hammers is entirely prohibited, by law. Further, a license is required to export rocks, minerals, and fossils from Norway.
Global positioning system (GPS) coordinates are given for most outcrops. “GEC” refers to coordinates derived from Google Earth. The two systems give the same coordinates, but the latter are less accurately positioned, largely because Google Earth currently has poor quality satellite images of East Finnmark. However, to make finding the outcrops easier, the positions of all the stops and locations can be plotted on Google Earth and the image then downloaded prior to undertaking the excursion. Much better quality images can be screen-dumped from http://www.1881.no/kart/#/ or from http://kart.statkart.no/.

Neoproterozoic Glacial and Associated Facies in the Tanafjord-Varangerfjord Area, Finnmark, North Norway
The Neoproterozoic glacial deposits of north Norway (snowball Earth Marinoan-aged Smalfjord and the younger Gaskiers-aged Mortensnes Formations) are superbly documented and illustrated in this comprehensive eight-day field guide. Lodgement, banded, deformation, flow, and melt-out diamictites derived from gneissic, clastic, and dolomitic sources are described, as well as glaciomarine, proglacial, and fluvioglacial sediments. Outcrops showing glaciotectonic folds, faults, flanking structures, shear-sense criteria (sigma-clasts), fluidized sediments, pro- and subglacial channels, iceberg dump structures, ghost clasts, dropstones, ice-crystal molds, and a ?kettle hole are included. The classic glacial striations at Oaibaccanjar'ga are described in detail. Marinoan cap dolostones overlying the Smalford Formation are included. In comparison to other Neoproterozoic glacial successions, this area is easily accessible by airplane and/or car, and most outcrops occur along the roadside or can be easily reached by small boat. This volume includes information about accommodations and small boat rental, and a fascinating summary of the natural and local history.
