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

Popis výsledku v původním jazyce

Fabric patterns of strongly serpentinized peridotite were determined using eigenvector analysis and eigenvalue classification of lattice preferred orientation of olivine and orthopyroxene. This approach has been applied to a rootless fold-shaped body ofmylonitized spinel to garnet peridotite surrounded by fine-grained and partially retrogressed ky-kfs granulite. The EBSD data show either axial [0 1 0] or [1 0 0](0 kl) pattern, both characteristic for 'dry' slip systems. The former pattern occurs predominantly along the inner margin and southern limb while the latter is mainly developed in the hinge of the fold shaped body. Foliations and lineations deciphered from the LPO data suggest that the [1 0 0](0 kl) pattern reflects constrictional deformation(prolate strain ellipsoid) in the hinge of the peridotite fold while the axial [0 1 0] pattern reflects pure flattening (oblate strain ellipsoid) inherited from the period of emplacement of the peridotite sheet in the crust.
