摘要：The Glacial Valleys in the basin of the Doamna River (the F.g.ra. Massif). The glacial valleys in the F.g.ra. Massif were first fluvial valleys occupied, eroded, enlarged and changed by the Pleistocene glaciers, so that they turned into spectacular troughs with new characteristics that make them different, but also integrate them with the fluvial valleys they developed from. This paper deals with the glacial valleys located in the basin of the Doamna River (southern side of F.g.ra. Massif): classification, morphometric and morphologic analysis of the long and cross profiles, genesis and evolution conclusions. The postglacial erosion (periglacial, fluvial, nival) destroyed many glacial microforms in these valleys, but those that preserved (partially) provide valuable clues on the extent and sizes of the Pleistocene glaciers (especially moraines and trimlines). In the Pleistocene, there were large valley glaciers (alpine glaciers) in the basin of the Doamna River. They occupied the origins of all developed pre-glacial valleys located near the main ridge of the F.g.ra. Massif. These valleys (the Valea Rea, the Bandea, the Zarna, the Leaota, the Br.tila) belonged to the Rau .es erosion complex, were adapted to structure, antecedent, and reached the main ridge of the F.g.ra. Massif by regressive erosion. There were 7 major glacial valleys of 2-7 km length in the basin of the Doamna River. They consisted of 2-3 steps/ basinets separated by glacial thresholds (of glacio-structural, glacio-lithologic or glacial nature)
