Abstract
Lozoya watershed is located in a Paleozoic rocky intracratonicorogen (NE Central System, Comunidad de Madrid, Spain).Afterwards of a detailed geomorphological mapping using GIS tools and high resolution DEM data (MDE5 CNIG), aerial photos, lithologic, topographic, and historic maps and field work, has allowed to distinguish 24 levels of terraces from the current level of the Lozoya River. These terrace system has been correlated with the fluvial terrace system formation of the Jarama River (Madrid Basin). Also we have fluvial deposits located in the karstic system of the archaeological site of the Pinilla Del Valle and at the cave of Reguerillo. Based on these correlations, we settled at the Early Pleistocene 13 levels of terraces of the Lozoya River, among T1 (+200-205 m) and T15 (+62-64 m), at the Middle Pleistocene 6 levels, among T16 (+50-55 m) and T20 (+17-20 m), at the Late Pleistocene 3 levels among T21 (+12-14 m) and T22 (+6-8 m) and at the Holocene 3 levels among T23 (+3-5 m), T24 (+1-2 m) and T25 (actual). Mapping and reconstruction of the base levels of the rock terraces has allowed us the modeling of the Quaternary evolution of the Lozoya Valley.
