The Porsanger Sandstone Formation and subjacent rocks in the Lakselv District, Finnmark, Northern Norway.
The Porsanger Sandstone Formation forms an imbricated thrust mass lying between the Precambrian Basement Complex to the south-east and an allochthonous nappe of \"Caledonian\" metamorphic rocks to the north-west. The Porsanger Sandstone Formation is separeted form the basement by a thin se...
