Connection between chemical zonation and crystallographic preferred orientation as an indicator for the fabric development in eclogites. Example from the Saxothuringian eclogites, Bohemian massif, Czech Republic
Finstad, Ane Kongsro (Master thesis; Mastergradsoppgave, 2017-05-15)The presence of eclogites is one of the strongest evidences for high pressure metamorphism, and for the presence of a paleo subduction zone. Deformation of eclogites can yield important information about the kinematics of subduction zones. The main mechanism for fabric development in eclogites is still a matter of debate among various research groups and has split the field in two. Most previous ... -
Transformation weakening: Diffusion creep in eclogites as a result of interaction of mineral reactions and deformation
Stunitz, Holger; Neufeld, Kai; Heilbronner, Renée; Finstad, Ane Kongsro; Konopásek, Jiří; Mackenzie, James R. (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-07-09)The deformation of eclogites and the driving forces for their fabric development are an important topic, potentially allowing to determine deformation rates and stresses in subduction zones, where the greatest number of large earthquakes occurs. Here, fabric studies of grain size and shape, texture, and chemical composition from two locations of Variscan and Alpine eclogites are presented. All samples ...
