East of Sjølisand in Rendalen the Moelv Tillite rests on the Ring Sandstone with an erosional contact. A wedge structure in the sandstone just beneath the Moelv Tillite is interpreted as a fossil ice wedge. A conglomerate, considered to have been deposited as a glaciofluvial gravel in a proglacial environment, occurs at the base of the Moelv Tillite. A tillite sheet within the conglomerate is thought to be a flow till deposit. The clast content of the Moelv Tillite indicates a glacial transport from the S or SW. The origin of the discontinuity surface is considered to be related to a eustatic lowering of sea level prior to glaciation of the region. A glacial deposition from a grounded ice sheet is discussed, likewise the palaeoclimatic implications of periglacial phenomena in the Late Precambrian tillites of northern and northwestern Europe.
