Abstract

Multiscale structural analysis, applied to the north-western and southern portions of the Thor-Odin dome, reveals that the tectonometamorphic evolution predating the development of the regional fabric (ST) is contrasted. Pre- ST PT-estimates range between amphibolite and granulite facies conditions: these different PTdt evolutions suggest the existence of different tectono-metamorphic units before the development of the Cordilleran transposition foliation.
