The pleistocene ice-sheet of c. 400—800 m in the Bellsund-area can be proved with the geomorphological analyses. The ascending of the ice-scour limit eastwards and the trough-valleys pointing to E prove a movement of ice-sheet from the E in the main-glacial period. At the exit of the fjord a second, lower ice-scour limit can be seen at about 120 m as a well marked ice-scour terrace inclined to W from the late-glacial time. The present glaciation corresponds to glacier-advances after the post-glacial warm-period. The glaciers of the small valleys had their maximal holocene extent in the positions of the end of the 19th century. Only the bigger glaciers at the end of the fjords show large and far-reaching moraines built of compressed holocene marine sediments. The glaciers in the field of research have nearly all retreated compared to maps of 1936. The fossil shore-lines of holocene age certainly reach till 60 m, probably till 85 m above present sea-level. Higher slopesteps till 264 m are structure-terraces with a spread of conglomerat-gravels. The uplift of the land is comprehended as an elasto-plastic reaction of the earth crust to the quartarnary ice-burden and ice-relieve impressed on an older tendency of uplift. The especially broad 20 m-terrace corresponds probably to a phase of compensation of the glacial-isostatic uplift of land and the glacial-eustatic uplift of sea-level. As the marine terraces are not tilted in the 70 km long area of the fjords, the uplift of the land occurred there in block, not parallel to the ice-burden, which deminished to the W, differently to the eastern parts of Spitsbergen. The regional results are compared with results from other regions of Spitsbergen.
