description: Presumable asynchronism of ice-marginal formations, belonging into one stage (e.g. Karukäpp et al. 1997; Boulton et al. 2001b) requires a revision of existing paleogeography of Termination in Estonia, which is based on synchronistic model of stadial endmoraines (Raukas et al. 1971). Furthermore, current paleogeographic models of the Termination has not been built on the basis of topography of these times, which differs from the current topography by the tectonic +/- component. Causative rela-tions between ice-terminal positions, meltwater outflows, topography and proglacial lakes has not been studied yet. Due to the elevated position of Saadjärve Drumlin Field, proglacial lakes in Peipsi and Võrtsjärv Basins were separated in the early stage of Termination of East-Central Estonia. Sediment accumulation in the lakes of Vooremaa has lasted througout the postglacial time (Pirrus et al. 1987), which makes the region promising for the research into Termination, for correlations and connection with the Holocene. Our main goals of the research are: 1. reconstruction(modelling) of hydrogeological conditions in deposits below ice, hydrodynamic pressure at the glacier bottom and meltwater hydrody-namics, based on the data, derived from the studies of ice-terminal formations and proglacial lakes; 2. GIS-based modelling of Late-Glacial water-bodies in the region, reconstruction and dating of water-levels, estimation and timing of isolations and mergings, correlation of these events with adjoining areas; 3. estimation of applyability of the event-stratigraphic methods in studying last Termination in Estonia and correction of Late-Glacial stratigraphy and varvochronological scale in Estonia; 4. const-ruction of time-palaeogeographic framework for studies in postglacial biota- and human settlement histories. If the main goals are achieved, we forsee the results as follows: 1. litho-, bio- and magneto-stratigraphic identification and timing of important palaeo-geographic and a magnitude stronger than nowadays climatic events, which occurred during the last Termination in Estonia; 2. correlation of established geo-events with adjoining areas (W-Estonia, NW-Russia, Gulf of Finland etc); 3. palaeo-geographic model of proglacial lakes will be compiled, taking account the topography of that time, tectonic movements and asynchronous character of ice-marginal formations; 4. applyability of event-stratigraphic methods in research into last Termination in Estonia will be claryfied.
