Description:
Extract Hans Stille (1876–1966), probably the most influential European geologist of the first half of the twentieth century, defined four principal tectonic phases responsible for the formation of the Variscan Orogen in Europe (Stille 1920). The first, the Breton Phase, occurred during Late Devonian–early Carboniferous time and was followed by the most important orogenic deformation event, the Sudetic Phase, which took place during early–late Carboniferous time. The younger deformation phases were represented by the Asturian (late Carboniferous) and Saalian (post-Carboniferous–early Permian) folding events. This chronological scheme was based on a sequence of deformation events defined by folding of stratigraphically well-constrained sedimentary strata followed by angular unconformity. Such an approach allowed the definition, to a relatively high precision, of the temporal and spatial extents of distinct crustal-scale deformation events throughout the whole European Variscan belt. ...
