The Glarus Thrust: Excursion Guide And Report Of A Field Trip Of The Swiss Tectonic Studies Group (swiss Geological Society, 14.-16.09.2006)

摘要

This excursion guide results form a field trip to the Glarus nappe complex organized by the Swiss Tectonic Studies Group in 2006. The aim of the excursion was to discuss old and recent concepts related to the evolution of the Glarus thrust. The major aspects were (ⅰ) the interplay between deformation, fluid flow and geochemical alteration, (ⅱ) episodic versus continuous deformation and fluid flow, and (ⅲ) the link between large-scale structures, microstruc-tures, and geochemical aspects. Despite 150 years of research in the Glarus nappe complex and the new results discussed during the excursion, there exist controversies that still are unsolved.
