The arc-derived upper units of the Órdenes Complex, NW Iberia, are emplaced above the Variscan suture and contain a low-grade metasedimentary uppermost section, with a maximum depositional age of 510–530Ma, intruded by a number of mafic dykes. Three deformational events affect the metasedimentary section. The youngest deformation event (D 3 ) is of undifferentiated Variscan age and consists...
The arc-derived upper terrane in the NW Iberia Variscan belt contains a 3000m thick turbiditic formation at its structural top. Most of the sandstones are feldspathic greywackes with a framework of quartz and weakly altered plagioclase. Rock fragments of vitric and microgranular texture are common in polymictic conglomerates and coarse-grained greywackes, together with slates, cherts and bipyramidal...
