The general extent and structural evolution of the southern Nagssugtoqidian orogen of West Greenland were first described by Hans Ramberg who based much of his paper on the deformation of the regional Kangâmiut dyke swarm. The southern boundary is m

Clusters of aligned, highly elongate, prismatic quartz (Qtz) rods occur in a few fayalite (Fa) crystals in an eulysite from a recently identified ∼1.8 Gy UHP site in central West Greenland (Glassley et al. 2014). Additional detailed analyses of the

The Nagssugtoqidian Orogen is a ca. 1.8 Ga belt of east-west trending, highly deformed rocks that bisects central Greenland. Although a variety of data have suggested this belt marks the location of a continent-continent collision zone, evidence of s

The stratigraphy of successions exposed in footwall crests of tilted fault blocks is commonly highly complex. Crestal stratigraphy and structure are particularly difficult to unravel in the subsurface due to poor seismic resolution across fault zones

The Nordre Stromfjord Shear Zone (NSSZ) in West Greenland is the northernmost zone of intense deformation within the 1.7–2.0 Gya Nagssugtoqidian Orogen (NO). The NO preserves a record of continent–continent collision and crustal-scale shearing as

The pre-Cretaceous basin evolution of the Feda Graben area in the vicinity of the Norwegian-Danish basin has been reconstructed utilizing geological and structural interpretation. The analysis reveals that the basin was faulted at its borders prior t

Serial cross-sections of faults within soft sediments of Miocene age, on the East coast of Denmark, were collated to provide 3D data sets with which to study the geometry of minor faults (displacements < 10 cm). From the wide variety of geometrical c

The Nordre Strømfjord shear zone is a 1.8 Ga zone of largescale, transcurrent and sinistral ductile shear (Sørensen et al. 2006) within the Nagssugtoqidian Mobile Belt (NMB) of central West Greenland. It has been hypothesised that the NMB is a sutu
