Effect of crystallography and temperature on the development of quartz high-angle grain boundaries in metamorphic rocks
Liebl, Christoph; Kuntcheva, Boriana;
; Kunze, Karsten (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Grain boundary migration during dynamic recrystallization of quartz results in grain boundary suturing of various extent. The geometry of the sutured boundaries is affected not only by temperature, strain rate, finite ... -
Microstructural evidence of impact-induced crystalplastic deformation and postshock annealing of quartz
; Spray, John G. (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
During impact, rocks at the surface and accessible depths encounter extreme conditions. The hydrostatic component of the shock wave-associatedstress, the so-called shock pressure, canreach several tens of GPa in the central ... -
Quartz microstructures in nature and experiment — evidence of rapid plastic deformation and subsequent annealing
; Stöckhert, Bernhard; Dorner, Dorothée; Küster, Martina; Röller, Klaus (11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)
Quartz microstructures produced in short-term deformation and annealing experiments are compared with those in naturally deformed vein quartz in cores from the Long Valley Exploratory Well (Long Valley Caldera, California). ... -
The effect of water, temperature and strain rate on the dislocation creep microstructure, recystallized grain size and flow stress of quartz
(11. Symposium "Tektonik, Struktur- und Kristallingeologie", 2006-03)Since the work of Griggs & Blacic (1965) it is well known that the crystal plastic flow strength of ‘wet’ quartz samples is much lower than that of ‘dry’ samples deformed at the same conditions, and the general effect of ...
