El vulcanismo alcalino, pre-Hettangiense, al NE de la Península Ibérica: puntos de interés para el Patrimonio Geológico

Abstract

Some alkaline basaltic sills, affected by spilitization processes, and other unaltered sills -including peridotite enclaves-, with the same chemical composition and setting age (pre-Hettangian), were studied in several areas of the Northeastern Iberia, with the best developed outcrops in Europe for this magmatism. A selection o f subjects and outcrops, including stratigraphic and structural data, shows clearly the interest of this alpine magmatism as part of the Geological Heritage
