| This compilation of stratigraphic and structural data accompanying the (re)issue of the 1:50000 sheets completes the project initiated by Prof. L.U. de Sitter in 1950. The total area mapped comprises about 400 km² in a strip more than 150 km from east to west. This part of the Hercynian tectogene is characterized by a very consistent sequence of Palaeozoic shelf sediments only interrupted by syn- to late-orogenetic flysch-molasse development. Neither of these sequences lend themselves to a simple geosynclinal model. Only the suprastructures of the orogene are exposed here; essentially decollement thrusting and folding. Fold and thrust vergences vary through 180° giving the centripetal pattern of the well-known Knee of Asturias. Very minor amounts of... |

| The structures along the southern boundary of the flysch-filled Yuso Basin bear witness to continuous epeirogenic activity during the Upper Carboniferous. The Carda\u0148o Line foems the boundary proper but other structures, somewhat similar to this fundamental feature e.g. the Pe\u0148a Prieta line, trend away into the basin subdividing it, demonstrating their control over deposition. Sedimentary structures indicate the instability of the deposits near the edge of this basin. The present structures have grown out of initial subbasins most probably by a simple continuation of a similar type of epeirogenic movements. Recrystallization of the shales into slates accompanied some of this deformation, the other rocks though recrystallised show little sign of an... |
