Abstract: This article presents the results of lineament and structural-geomorphological analysis of the part of Karelian coast of the White Sea. The coasts of the Kandalaksha Gulf have significantly uplifted in the Neotectonic time; this is the territory of most intense post-glacial rise within the Baltic shield. A combination of glacio-isostatic compensational uplift after deglaciation, tectonic movements and eustatic sea level uplift has formed the modern image of coastland. The goal of this work lies in determining the existence of differentiated movements of crustal blocks on a scale of smaller blocks, which size does not exceed several tens of kilometers. The authors conducted the lineament and structural-geomorphologic analysis based on the field data, literary material and remotely sensed data. The data on the relative sea level changes in the regions, acquired mostly via the method of isolated basins, was imposed upon the obtained maps demonstrating lineaments and blocks. The authors assess the pace of the relative uplift of the blocks, their spatial and temporal change. The presence of graded block movements with differences in amplitudes reaching 20 m. Their character of such graded movements overall corresponds with distribution common to glacio-isostatic uplift, at maximum speed, gravitating towards the center of glaciation; however, the position of the most rapidly uplifting Rugozerko-Kuzakotskiy block can be explained only by the tectonic movements. It is revealed that a significant role in development of the structural plan of the territory was played by the reactivated Onega-Kandalaksha paleorift. It is demonstrated that its northwestern branch has different pressure that the central, which confirms the fact that this part of graben originated at Neotectonic stage.
