Summary
The superficial deposits within the map-sheet Hølonda were formed during the Late Weichselian and Holocene. At the time of deglaciation the sea-level was situated ca. 175 m above the present one, and fine-grained marine sediments were deposited distal to ice-marginal glaciofluvial deposits. In the central part of the map area the superficial deposits are dominated by till and glaciofluvial sediments. In the mountainous areas the till cover is generally thin and discontinous. The ice recession occurred during the Allerød (12 000-11 000 years B.P.), but remnants of glacier may still have remained in the central part of Hølonda during an early Younger Dryas glacier advance, taking place 10 800-10 500 years B.P. Short accounts are given of geological processes during the Late Weichselian and Holocene. The potential for different utilization of the superficial deposits is also briefly discussed.
