Origin of Plastic Deformation in Olivine and Pyroxene.
Abstract
Experimentally and naturally deformed olivines, orthopyroxenes and amphiboles have been investigated by transmission electron microscopy to determine the dislocation substructure. Several sets of substructures have been determined and these have been combined with high temperature determinations of the crystal structure in an attempt to explain variations in operative slip system with temperature. This goal has been achieved only partially; a theoretical model was devised to account for twin-gliding in amphiboles and initial work was done in attempting to model the enstatite-clinoenstatite transformation from an energetical point of view. The nature of exsolution lamellae in orthopyroxenes and amphiboles was also examined by TEM means. (Author)
