The Permian and Triassic of the central Cantabrian Mountains (Eastern Asturias- Western Cantabria, N Spain)

Abstract

This field trip shows new data based on recent work by the organizing research team. These data show a new stratigraphic chart based on precise ages of each defined unit, a reinterpretation of their sedimentary evolution and the development of a new Variscan-Alpine tectono-sedimentary framework. Furthermore, the new data reveal for the time a similar geodynamic evolution across the Pyrenean-Cantabrian basins at the end of the Variscan cycle and even with those formed within Western and Central Europe during the early-middle Permian. This new obtained information is based on a multidisciplinary work, including geological mapping, sedimentology, mineralogy, petrology of volcanic rocks and new paleontological data.
