Shear zones in foliated rocks: geometry and kinematics. These differences refer to:.In addition to this second point, the presence of a pre-existing foliation induces the development of minor structures arising from buckling instabilities formed at the marginal domains. These questions are reviewed and illustrated with examples taken from the Cap de Cr

Development of compressional and extensional structures during progressive ductile shearing, Main Ceser Himachal Himalaya the MCTZ is well preserved in a half-klippe around the Chur peak. The ductile shearing related to the formation of the MCTZ was superimposed on strongly anisotropic metasedimentary rock sequences in which two phases of folding precede the ductile shearing event. Compressional s

Deformed lineation in ductile shear zones: a case study from the Proterozoic fold belt of Singhbhum,s. The commonly observed stretching lineation indicates the direction of movement. In most models of heterogeneous simple shear the C-surfaces are regarded as invariant, and remain planar during progressive deformation. However, it is well known that perturbations in the flow regime caused by slight

Construction and prospective use of displacement-difference vectors (DDVs) in vertical sections acroing actual DDV fields in deformed rock masses. This paper outlines a method of determining DDV rows which is tailored for use in partly eroded belts of ductile dip shear. The method employs arbitrary points on a strained material line coincident with the cross-sectional trace of the erosion surface.

Strain and crystallographic fabric pattern in a folded calcite vein: the dependence on initial fabriing in the outer arc of a fold and layer-parallel shortening in the inner arc, with a neutral surface separating the two. We describe a folded fibrous calcite vein in which the primary crystallographic fabric, with c-axes perpendicular to the vein walls, allows only for layer shortening by twinning

Normal faulting and exhumation of metamorphic rocks in mountain beltslts in important crustal thickening and formation of high relief giving rise to intensive erosion. Erosional unloading causes the buoyant crustal slice to be exhumed at a rate comparable with the subduction rate..This process seems to work in different collisional belts explaining rapid syn-collisio

Evolution of salients in a fold- and-thrust belt: the effects of sedimentary basin geometry, strain elf, lithotectonic stratigraphy of the sedimentary package, and deformation conditions (determined mainly by variations in the geothermal gradient). The differences in structural geometry and tectonic evolution between adjoining segments of the FTB result from broad variations in original taper, lit
