Inyecciones de conglomerados en el Triásico de Pálmaces de Jadraque (Guadalajara)

Abstract

Conglomerate dykes have been observed in Buntsandstenin deposits surrounding of Palmaces de Jadraque dam (Spanish Central System southeast border). Deformed sediments by liquefaction correspond to fluvial systems of mixed load rivers of gravels and sands. Conglomerate dykes have a true tectonic control. These structures have a mean trend NW-SE and another perpendicular one, are less developed. These trends are compatible with extensional process proposed by different authors for this time. Due to tectonic control as well as the associated tectonic extensional process, liquefactions trigger mechanism could be seismic.
