Resumo: | This study addresses coastal terrace staircases of western central Portugal (Cape Mondego to Cape Espichel). Below the culminant marine unit, that records the last episode of aggradation before the ongoing stage of incision, several terrace levels are identified. The following methodology was used: a) production of geomorphological maps, combining analysis of detailed MDT’s and aerial photos, with field surveys calibrated with GPS data; b) stratigraphic and sedimentological study of the sedimentary deposits associated with the marine platforms; c) luminescence dating. On each terrace staircase, the number of platforms and their elevations are different, indicating differential uplift. Quartz OSL provided age estimates up ca. 150 kyr and post-IR IRSL on K-feldspar up to ca. 700 kyr for the marine terraces under study. Using the culminant platform as reference and assuming that it is 3.6 Ma old, uplift rates were estimated as ranging from 0.071 m/ky to 0.019 m/ky. The ongoing luminescence dating will provide the uplift rates estimated for the lower and middle marine terraces |

This study addresses coastal terrace staircases of western central Portugal (Cape Mondego to Cape Espichel). Below the culminant marine unit, that records the last episode of aggradation before the ongoing stage of incision, several terrace levels are identified. The following methodology was used: a) production of geomorphological maps, combining analysis of detailed MDT’s and aerial photos, with field surveys calibrated with GPS data; b) stratigraphic and sedimentological study of the sedimentary deposits associated with the marine platforms; c) luminescence dating. On each terrace staircase, the number of platforms and their elevations are different, indicating differential uplift. Quartz OSL provided age estimates up ca. 150 kyr and post-IR IRSL on K-feldspar up to ca. 700 kyr for the marine terraces under study. Using the culminant platform as reference and assuming that it is 3.6 Ma old, uplift rates were estimated as ranging from 0.071 m/ky to 0.019 m/ky. The ongoing luminescence dating will provide the uplift rates estimated for the lower and middle marine terraces |
