In order to clarify the problem, the authors of the present study selected two lines of research: 1)detailed geomorphologic mapping; and 2)laboratory analysis of the glacial deposits. This sedimentological study, which had not been carried out before in the area, proved to be very significant for the diagnosis of the style and extent of the glaciation. We can confirm the Serra do Ger\u00eas glaciaion. The vestiges are particularly clear and important on the Eastern side of the mountain and in the Fafi\u00e3o valley, where the most important glacigenic sediment complex is found. At the glaciation maximum, an ice dome reached the thickness of some 150m in both the Couce and the Compadre areas, from whence outlet glaciers radiated into the main peripheral valleys. At that time the upstream sector of the Homem Valley glacier must have reached the thickness of about 300m. Recent absolute dating, using cosmogenic isotopes in glaciated granitic surfaces, suggested that the glaciation maximum in the Ger\u00eas is older than the Last Glaciation.<\/jats:p>","DOI":"10.18055\/finis1669","type":"journal-article","created":{"date-parts":[[2016,11,17]],"date-time":"2016-11-17T13:20:47Z","timestamp":1479388847000},"source":"Crossref","is-referenced-by-count":1,"title":["A Glacia\u00e7\u00e3o plistoc\u00e9nica na Serra do Ger\u00eas"],"prefix":"10.18055","volume":"35","author":[{"given":"Ant\u00f3nio Brum","family":"Ferreira","sequence":"first","affiliation":[]},{"given":"Juan Vidal","family":"Roman\u00ed","sequence":"additional","affiliation":[]},{"given":"Jos\u00e9 Lu\u00eds","family":"Z\u00eazere","sequence":"additional","affiliation":[]},{"given":"Maria Lu\u00edsa","family":"Rodrigues","sequence":"additional","affiliation":[]}],"member":"7614","published-online":{"date-parts":[[2012,12,13]]},"container-title":["Finisterra"],"original-title":[],"link":[{"URL":"http:\/\/revistas.rcaap.pt\/finisterra\/article\/viewFile\/1669\/1363","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/revistas.rcaap.pt\/finisterra\/article\/viewFile\/1669\/1363","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,11,17]],"date-time":"2016-11-17T13:27:25Z","timestamp":1479389245000},"score":1,"resource":{"primary":{"URL":"http:\/\/revistas.rcaap.pt\/finisterra\/article\/view\/1669"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,12,13]]},"references-count":0,"journal-issue":{"issue":"69","published-online":{"date-parts":[[2012,12,13]]}},"URL":"https:\/\/doi.org\/10.18055\/finis1669","relation":{},"ISSN":["0430-5027"],"issn-type":[{"value":"0430-5027","type":"print"}],"subject":[],"published":{"date-parts":[[2012,12,13]]}}}
