Sedimentological characterization of Upper Miocene-Pliocene fluviolacustrine and tuffaceous systems of the Calatayud Basin (Zaragoza)

Abstract

A complex fluviolacustrine calcareous system with associated autochtonous tufa deposits is recognized in the Upper Miocene-Pliocene of the Neogene Calatayud Basin. A detailed sedimentological analysis of the calcareous sediments reveals a wide spectrum óf facies associations mainly related to reworking of tufa deposits including products such as oncolithic tufas and less common phytoclastic and intraclastic tufa
