Åmark, Max 1986 06 01: Glacial tectonics and deposition of stratified drift during formation of tills beneath an active glacier – examples from Skåne, southern Sweden. Boreas , Vol. 15, pp. 155–171. Oslo. ISSN 0300–9483. Three exposures in till have been investigated in Skåne, southern Sweden. The tills were deposited at the base of an active glacier, and are largely made up of subglacially deposited stratified drift. Deformation of the till took place syndepositionally, resulting in high‐angle fractures, clastic dikes, shear planes and folds, and in irregular deformational structures. The stratified drift was transformed into a more or less diamicton‐like material by the deformation. The orientation of clasts was influenced by the action of the subglacial meltwater and the shearing from the overriding glacier. The tills accumulated at most 100 km inside the margin of the receding glacier.
