INGENIØRGEOLOGI

The superficial Quaternary deposits occuring within the map-sheet area have been classified and mapped according to their genesis. Fine-grained marine deposits dominates in the main valley below the highest postglacial sea-level. c. 1973 m a.s.l. Numerous glaciofluvially ice-contact deposits are situated in the main valley too, but only the nothernmost was built up to the sea level (true deltas). During the postglacial isostatic uplift, the rivers retransported the glaciofluvial deposits and most of this material was deposited as regression-deltas at lower levels. Above the highest sea level quaternary deposits are almost lacking except for scattered till.
Løsmasse og arealbruk: The utilization and evaluation of the superficial deposits with regards to cultivation, forestry, waste disposal, engineering, groundwater, sand and gravel resources and nature conservation, are discussed. A field trip guide to the area is presented.

Boringene foregikk på grunnlag av forutgående seismiske målinger, jfr. GM Rapport nr. 109. Det ble boret ett hull som traff fjell etter 23,50 meter.
