A. Flat basal unconformity and north-directed downlap of the conglomerates in the Serra de Pessonada. Field of view is 5 km. B. Ermita and Pallaresa allogroups onlapping against the irregular basal unconformity in the Flamisell valley (Serra de Montsor). The horizontal dip of the beds is apparent due to the orientation of the photo. Tilting of the beds ranges from 20°N at the bottom of the Pallaresa allogroup to nearly horizontal at the top. Field of view is 6 km. C. Onlap of the Pallaresa allogroup conglomerates (Camporan system) against the Lower Cretaceous ridge in the northern Gurp basin. Field of view is 4 km. D. Pallaresa allogroup conglomerates (Roca del Pesó system) infilling Lower Cretaceous palaeoreliefs in the NE margin of the Organyà basin. Field of view is 2 km.
