Resumen de Control tectónico y distribución de las facies en el tránsito Triásico-Jurásico en el sector de Oliete (Teruel)
Ana Pilar Bordonaba, Marcos Aurell Cardona, Antonio María Casas Sáinz
Facies and thickness distribution in the Cortes de Tajuña Fm. was controlled by extensional fault activity around the Triassic-Jurassic boundary in the Iberian basin. The analysis of the outcrops located South of Oliete (Teruel) allows the mapping of a East-West trending normal fault (inverted as a thrust during Alpine compression), which involved the presence of a thick carbonatic aand evaporitic succession (up to 300 m) in the hanging wall. Thickness in the foot wall is reduced to a third. Two facies associations are found in the lower part of the unit. Relatively deep facies (intertidal to shallow subtidal) laterally grade into evaporites and lutites (supratidal sabkhas) in the areas were subsidence was lower. In the upper part are found massive dolomites and well-bedded limestones all across the study area
