Geomorphology of the northern sector of the Alfambra- Teruel depression (Iberian Ranges, NE Spain)

Abstract

The area of Alfambra (NE Spain) is very representative of the relief evolution of the Eastern Iberian ranges. It contains the main geomorphological elements that illustrate this evolutionary process. The geomorphological cartography includes the northern sector of the Alfambra-Teruel Neogene depression and its mountainous surroundings. The cartographic process started by using aerial photographs (1:30000 scale) and fieldwork. Later, the document was projected to the UTM Zone 30 system with ETRS_1989 Datum introduced to ArcGIS 10.1. The legend follows a chronological order. The structural reliefs, erosion surfaces, karst landforms, Quaternary pediments and terraces, and fluvial network are represented over a lithological background. The main cartography is complemented with two maps of lithological and geomorphological units. The obtained information enabled the main geological and geomorphological stages of the regional relief to be established.
