Abstract :This paper presents for the first time data regarding the evolution of Drini Bay (Adriatic Sea) coastal plain since LGM (20 Ka BP). This area is very poorly studied by both Albanian and foreign researchers. A database including data from 200 borehole logs performed during different field campaigns undertaken in this area since 1953 was created with the purpose to determine the lowest sea level reached during LGM. The field observation helped us to evidence the presence of sea level indicators on the slopes of the carbonate hills surrounding the coastal plain. Two indicators represented by "wave cuts” or "tidal notched” were distinguished. The first one at an altitude 30-40 m, which probably belongs to the higher sea level reached during MIS5.5 and a second one, at an altitude of 9-10 m, which probably belongs to the Maximum Flooding Surface of the last transgression. The position of MIS5.5 sea level indicator suggests that the area was under the conditions of a tectonic uplift. Based on data at our disposal, we have calculated that the contribute of glacio-isostatic and hydro-isostatic components in this area during last 20 ka varies between 1.05 and 1.35 mm y -1 .Keywords : Drini Bay, coastal plain, MIS5.5, LGM, MFS
