With great pleasure, we would like to invite you to an open lecture „Deformed Dirt: the deformation caused by glaciers and ice sheets” which will be given by Prof. Emrys Phillips from British Geological Survey.
The lecture is organized as part of the “Research University Excellence Initiative” (IDUB) program and will take place during the Scientific Webinar of the Institute of Geological Sciences UWr on Tuesday, March 21, 2024 at 3:00 p.m., hybrid:
– In lecture room no. 220 in the Institute of Geological Sciences UWr (9, Maks Born Square, Wrocław, II floor) as well as – online in TEAMS

Abstract
This lecture will focus on the deformation caused as a glacier or ice sheet pushes into and overrides pre-existing (older) sediments and/or bedrock. This deformation, known as glacitectonism, results in the development of a range of structures (folds, faults, foliations) structures similar to those found in orogenic mountain belts, but on a smaller scale and over much shorter time scales. The lecture will include a brief history of glacitectonic research, then using classic examples from around the world (including Canada, Iceland and the UK) will provide an introduction to the range of landforms and large- and microscale deformation structures formed as a result of glacitectonism. It will finish by showing why understanding glacial deformation processes has become so important in the development of offshore windfarms using an example from Dogger Bank in the North Sea.
Biography of Professor Emrys Phillips (British Geological Survey)
Professor Phillips has worked at the British Geological Survey (BGS) in Edinburgh for 34 years and is a senior research scientist specialising in the deformation of geological materials (rocks and sediments). His expertise is in the micro- and macroscale analysis of the soft-sediment deformation of glacial sediments and how it effects the stability and dynamics of modern and former glaciers and ice sheets. He joined BGS in 1990 as a member of the Mineralogy and Petrology Group and his role since that time has been to provide detailed specialist scientific input into BGS’ multidisciplinary science programme. Emrys has worked on a variety of research and commercial projects throughout the UK (Scotland, England and Wales), Iceland, North America (Canada – e.g. Newfoundland, Labrador, Alberta, Saskatchewan), Africa (Botswana, Egypt), Europe (Germany, Poland) and the Middle East (United Arab Emirates, Oman, Saudi Arabia), as well as increasingly within the UK offshore (Irish Sea and North Sea – e.g. Dogger Bank, Dudgeon, Orkney).
