“…The Villafranchian pediments that spread towards the basin do not necessarily represent this rearrangement (Gutiérrez et al 1996(Gutiérrez et al , 2008, since alluvial systems laterally grading into endorheic palustrine areas have been documented from early Pleistocene times, for example, in the Teruel area (Ezquerro et al 2012), and have even persisted to the present in the Gallocanta depression (Gutiérrez et al 1996) and the southern Jiloca Basin (El Cañizar lake; Rubio, 2004;Rubio & Simón, 2007). The Jiloca river, the main tributary of the Jalón river, captured the Jiloca graben during early Pleistocene time (Gutiérrez et al 1996(Gutiérrez et al , 2008(Gutiérrez et al , 2020Vacherat et al 2018), becoming the longitudinal drainage of the Calatayud Basin, together with the primitive Perejiles and Grío rivers (Fig. 1c).…”

“…The transition from endorheic to exorheic conditions in the study area is associated with the capture process of the Calatayud Basin. According to morphological and stratigraphical evidence, this is a diachronic process active since late Miocene time, which started with the capture of a primitive Jalón river NW of the Algairén and Vicor Ranges (Gutiérrez et al 1996(Gutiérrez et al , 2008(Gutiérrez et al , 2020Fig. 1c).…”

The NNW–SSE-trending extensional Río Grío–Pancrudo Fault Zone is a large-scale structure that obliquely cuts the Neogene NW–SE Calatayud Basin. Its negative inversion during the Neogene–Quaternary extension gave rise to structural and geomorphological rearrangement of the basin margin. Geological mapping has allowed two right-relayed fault segments to be distinguished, whose recent extensional activity has been mainly characterized using a deformed planation surface (Fundamental Erosion Surface (FES) 3; 3.5 Ma) as a geomorphic marker. Normal slip along the Río Grío–Lanzuela Fault Segment has induced hanging-wall tilting, subsequent drainage reversal at the Güeimil valley after the Pliocene–Pleistocene transition, as well as morphological scarps and surficial ruptures in Pleistocene materials. In this sector, an offset of FES3 indicates a total throw of c. 240 m, resulting in a slip rate of 0.07 mm a–1, while retrodeformation of hanging-wall tilting affecting a younger piedmont surface allows the calculation of a minimum throw in the range of 140–220 m after the Pliocene–Pleistocene transition, with a minimum slip rate of 0.07–0.11 mm a–1. For the late Pleistocene period, vertical displacement of c. 20 m of a sedimentary level dated to 66.6 ± 6.5 ka yields a slip rate approaching 0.30–0.36 mm a–1. At the Cucalón–Pancrudo Fault Segment, the offset of FES3 allows the calculation of a maximum vertical slip of 300 m for the last 3.5 Ma, and hence a net slip rate close to 0.09 mm a–1. Totalling c. 88 km in length, the Río Grío–Pancrudo Fault Zone could be the largest recent macrostructure in the Iberian Chain, probably active, with the corresponding undeniable seismogenic potential.

“…Quaternary tectonics is evidenced by the presence of active faults in the eastern margin of the Alfambra-Teruel graben and the north fault of the Jiloca graben (Concud sector). Both were studied to know the activity ages (Arlegui et al, 2004;Lafuente, 2011;Lafuente et al, 2011Lafuente et al, , 2016Simón et al, 2012Simón et al, , 2016Gutiérrez et al, 2020).…”

“…Reliable ages of Holocene stratified screes were subsequently determined by 14 C (Peña-Monné et al, 2017) and geoarchaeological studies combined with 14 C dating allowed the definition of accumulation-downcutting phases during the late Holocene (Peña Monné, 2018). There has been extensive dating of Pleistocene terraces and other deposits, such as tufas and slopes dated by OSL, ESR and U/Th methods, affected by neotectonic activity around the junction of the Jiloca and Alfambra-Teruel grabens (e.g., Arlegui et al, 2004;Gutiérrez et al, 2008Gutiérrez et al, , 2020Lafuente, 2011;Lafuente et al 2011Lafuente et al , 2014Simón et al, 2012), while Santonja et al (2014) and Duval et al (2017) obtained numerical ages from the Pleistocene (Lower to Middle Paleolithic) Cuesta de la Bajada Paleolithic site located at the terrace sequence of the Alfambra River.…”

The Zagros Fold‐Thrust Belt is a tectonically active region within the Alpine‐Himalayan orogenic system resulting from ongoing convergence between Afro‐Arabian and Central Iranian plates. The presence of various geomorphic features in this region provides an ideal natural case for identifying deformed landforms resulting from active tectonics. The relative tectonic activity along the Lar and Didehban faults within the Zagros Fold‐Thrust Belt, SW Iran was evaluated using six DEM‐derived geomorphic indices: the stream‐gradient index (SL), drainage basin asymmetry (AF), hypsometric integral (HI), valley floor width‐valley height ratio (Vf), drainage basin shape (Bs), and mountain‐front sinuosity (Smf). These indices were combined to yield the relative active tectonics index (Iat) that allows the variation of tectonic activity along the Lar and Didehban faults to be related to variations in rates of incision, tectonic tilting and uplift. This variable tectonic activity was characterized by different Iat values along the faults. The low to high relative tectonic activity (class 1: 1 < Iat < 1.5, class 2: 1.5 < Iat < 2, class 3: 2 < Iat < 2.5, class 4: 2.5 < Iat) correlates with variable geomorphic features along the faults. The results of this study present an approach for assessing the effects of active tectonics and also for sustainable land use planning over a large area.
