A little about the rocks at Kongsfjord:
The rocks on the Varanger peninsula’s Precambrian, layered sedimentary rocks. They consist mainly of sandstone and shale deposited originally as sand and silt along the rim of an ancient continent, between 600 and 850 million years ago. Tectonics led then to the rocks on the northern half of the Varanger peninsula was pushed into the area from the west. This movement occurred along a fault. We see it in the terrain as a recess which runs from Trollfjorden west, past Geatnjajávri on Kongsfjordfjellet, to Komagelv east.
Among the rocks north of Trollfjord- Komagelv- Rejection we find sheer layer of dyphavssandstein and siltstone (turbidite) associated Kongsfjord Formation. They are particularly well exposed in roadcut along the coast east of Kongsfjorden.
