Abstract
This thesis produced new pressure–temperature–time constraints on the 4D evolution of the southern Western Gneiss Complex (WGC) and overlying rocks, confirming that the Nordfjord–Sogn detachment (NSD) played a key role in developing their present-day positions. This coupled with data from further north lending weight to the WGC exhuming from flat-slab conditions. Recognition of large amounts of mechanical heating surrounding the NSD was key, with potential implications to large-scale crustal structures.
