Ductile deformation and rheology of sub-continental mantle in a hot collisional orogeny: Example from the Bohemian Massif

► Structural and microstructural study of granulite and embedded peridotite. ► Eigenvector analysis and eigenvalue classification of lattice preferred orientation. ► Coupled deformation between granulite and peridotite. ► Peridotite embedded within the felsic lower crust is viscously deformable.
