Crystallographic preferred orientations in eclogites – A review

摘要: Abstract During the last decades, processes taking place in subduction zones have been a topic of extensive debate. There are many models on tectonic scale, but knowledge deformation at microscopic levels is essential for an understanding involved. Crystallographic preferred orientation (CPO) investigations minerals eclogites yield possibility to study crustal part subducted oceanic lithosphere, as well continental units containing basic intrusions, which frequently exhumed during collision. From CPO data omphacite and garnet, other constituent eclogites, conclusions stress strain depth currently active can be drawn, pressure-temperature path now rocks unraveled. This contribution provides overview studies concerning slip systems, deformation, possible forming mechanisms all major mineral phases implications these microstructural zone discussed. Nevertheless, there still open questions future research essential.
