Sea cliff at Wissower Bach (Pleistocene stripe 5) – microstructural evidence of large-scale glacitectonism and glacier kinematics

Abstract

Abstract. Soft-sediment thin sections from a SW-dipping thrust fault at the south-western limb of the Wissower Bach syncline (NE Rügen) give rise to the complicated glacitectonic environment in the south-western Baltic Sea region. Micromorphology, microstructural mapping, and macroscale information have led to the development of a detailed model for the evolution of the syncline during late Weichselian glacitectonism.

Glacial microsedimentology—a new lens to investigate glacial sediments—a review

“…Robinson et al, 2021). In applying structural geological methods (Ferguson et al, 2011;Phillips et al, 2011Phillips et al, , 2018Lee et al, 2013;Neudorf et al, 2015;Gehrmann et al, 2017Gehrmann et al, , 2019Brumme et al, 2019;Kettler et al, 2021) a better understanding of subglacial till mechanisms and architecture has emerged. For example, Menzies and Whiteman (2009) devised a method of sediment typing or fingerprinting by dividing a thin section in squares, tracing microstructures on the cover glass and then counting the different microstructures and applying a Chi square test to differentiate.…”

“…Microsedimentology is increasingly being used as a primary tool for the analysis of glacial sediments (cf. Hart and Rose, 2001;Ferguson et al, 2011;Gehrmann et al, 2017Gehrmann et al, , 2019Hart, 2017;Phillips et al, 2018;Kowalska et al, 2020). These analytical techniques provide far greater detail about the depositional and deformation histories of these sediments than obtained from macroscale studies alone and provide critical insights in unravelling complex deformation histories recorded by glacigenic sequences.…”
