• Resumen

  • The Galve subbasin, which lies in the central part of the Teruel province in east-central Spain, was a region of continental sedimentation during the Early Cretaceous (Figure 1; see also Figure 1 in Soria et al. ,this volume, concerning an overview of the geology and tectonics of the Iberian basin). The Galve subbasinlies on the margins of the Maestrazgo tectonic domain (Salas and Cuimera, 1996; Soria, 1997; Soria et al., this volume). Outcrops with a northwest-southeast trend are exposed between the villages of Aliaga and Galve north and Alcalá de la Selva and Gudar in the south (Figure 1).The Galve subbasin is separated from the Pefiagolo sasubbasin, which lies to the southwest, by the Sierra of Moratilla uplands. The main structural feature of this range is the Alcalá de la Selva anticline,which has a core of Jurassic and Triassic rocks and was formed by compressional reactivation of the Alcalá de la Selva basement fault. The latter acted asa normal fault during Cretaceous sedimentation(Salas and Guimera, 1996). The Ejulve-Fortanete high, which represents the eastern edge of the Galve sub basin, is structurally a north-northwest-south southeast trending syncline with a core of Upper Cretaceous and Tertiary rocks (Soria et al., 1995). During sedimentation, the northern boundary of the subbasin was defined by a series of east-northeast west-southwest to east-west trending normal listric faults that separated this subbasin from the Las Parras subbasin (Figure 1). These normal faults became 295 inverted during phases of Tertiary compression (Guimera and Salas, 1996).
