Neotectonic processes in marine terrace sediments near Canero (Western Asturias)

The Pleistocene sediments deposited on the emerged marine abrasion platform near Canero village (Valdés, Asturias) are truncated by reverse faults which are parallel to basement bedding. These structures imply a neotectonic activity with a NW-SE maximum compressive stress, consistent with recent fault population analysis and current seismicity studies. The described deformation corresponds to a reactivation of folds in the Palaeozoic basement through a flexural slip mechanism, with the subsequent accommodation of the unconformable Pleistocene cove

New remorks about sulfate ores of the near Gijón (Asturias)

A borehole drilled in the only gypsum mine of Asturias has shown the existence of anhydrite and gypsum at depths greater than presently exploited. These stratiform deposits were laid down in distal flood plains, tidal f/ats an sabkha environment

Precisiones sobre el Cretácico superior del subsuelo urbano de Oviedo

The top of the Cretaceous section at Oviedo has been studied from the stratigraphic, petrographic and paleontological point of view, in order to increase the knowledge of a previosly little know sequence. An abundant microfossil assemblage found there permitted dating it, for the first time, as of Santonian ag

Problematic of Upper Cretaceous limestones in the foundations of Oviedo city

In rocky substratum of Oviedo (N Spain) there is an important carbonate formation of Upper Cretaceous age. This level has interest into applied geology on having supposed a surface of preferential foundation for city buildings and, in fact, mechanical laboratory tests show that its geotechnical behavior is very good. Nevertheless some punctual deficiencies like karstification processes appear at these limestones, involving a certain risk of zonal failure in structures foundation
