Evidence for contemporaneous yet contrasting styles of granite magmatism during extensional collapse of the northeast Greenland Caledonides

Article Abstract:

The northeast Greenland Caledonides were studied and evidence for contemporaneous, although contrasting, styles of granite magmatism during extensional collapse was found.

Regional Caledonian structure within an oblique convergence zone, Dronning Louise Land, NE Greenland

Article Abstract:

Complex deformations in the East Greenland Caledonides structures indicate that an oblique collision occured between the Laurentia and Baltica cratons approximately during the Devonian Period. Models show that the metamorphisms are due to a sinistral strike-slip transpression followed by back-stepping and back-collapse in the oblique ductile thrusting zone. There is evidence that the fault system is on a scale of major intracontinental shear zones.

Structure and early kinematic history of the Great Glen Fault Zone, Scotland

Article Abstract:

The Great Glen Fault Zone (GGFZ) is part of the lower Paleozoic Caledonian orogenic belt of the British Isles is an example of a major strike-slip fault with a history of reactivation, formed in the orogenic cycle. A detailed structural study of the GGFZ provided an analysis of shear zones, faults, and mesoscopic and microscopic structures, confirming the pre-Late Devonian sinistral displacement previously inferred.
