Isbevegelse i Lillehammer-området, Sør-Norge, under siste nedising.

Abstract

The ice movement from the last glaciation in the northern part of the lake Mjøsa district are presented in an ice phase model. Four main ice phases are reconstructed mainly based on striation, but fluted surfaces, poorly developed drumlins, marginal moraines, erratics and till stratigraphy have been recorded and are also incorporated in the model. The ice movement directions in the inland ice phase are found to vary between SSW and SSE in the investigated area. No evidence was found for an ice divide located in or south of the Lillehammer area as previously proposed. Ice movement patterns in the deglaciation period are reinterpreted. Earlier, the ice movements in the deglaciation period were believed to have been directed towards south-east in the northern part of the lake Mjøsa district. This is found to be true for the last part of the deglaciation period, whereas the early part was dominated by an ice movement direction towards east to east-southeast in the investigated area.
