Description
Summary:In mainland Norway, Mesozoic sedimentary rocks (Jurassic and Cretaceous) outcrop only on Andøya. These are the youngest rocks on land anywhere in Norway. Triassic dykes occur in West Norway, while Mesozoic structures and fault products are common at major and minor fault zones in various parts of coastal Norway. Sedimentary rocks occur in half-grabens in many fjords, especially in Mid Norway and northern Nordland. Most of these are of Middle-Late Jurassic age, and are interpreted to represent the remains of a much more extensive Jurassic-Cretaceous sedimentary succession that covered large parts of coastal Norway. These sedimentary rocks were downfaulted during tectonic activity in Late Jurassic-Early Cretaceous times thus escaping late Tertiary-Pleistocene erosion. 56211
