Tectonic succession of the Caledonian nappe front in the Haukelisæter- Røldal area, Southwest Norway.
Abstract
It is concluded from reconnaissance studies on Hardangervidda that a succession of 5 allochthonous units occurs above the Precambrian basement and its autochthonous\/parautochthonous cover. The units are named from bottom to top: Holmsjø Formation, Dyrskard Group, Nupsfonn Complex, Kvitenut Complex and Revsegg Formation. Metamorphism in granulite facies (Kvitenut Complex) and subsequent amphibolite facies (upper 4 units) took place outside the present area. Movement between the units occurred in the Precambrian as well as during late Caledonian tectonic phases.
