Variations of fluvial tufa sub-environments in a tectonically active basin, Pleistocene Teruel Basin, NE Spain

Our results point out that the location, morphology and sedimentary sequences of the Tortajada fluvial system had an important tectonic control. The situation of the main and secondary faults controlled the paleomorphology of the river floor. Thus cascades are found in areas of important step faults, whereas the spaces between faults were occupied by fluviatile/lacustrine areas. In addition the development of the different sedimentary sequences was also a reflection of movements of these faults. In short, our study may confirm that tectonism is an important control on tufa development.
