Inclined transpression can be defined in terms of simultaneous contraction and strike-slip and dip-slip shearing, and is illustrated here using a strain triangle in which the apices represent the three strain components. Strain matrix modelling shows that all three axes of the finite strain ellipsoid are non-parallel to the Cartesian reference frame ...

Transpression is considered as a wrench or transcurrent shear accompanied by horizontal shortening across, and vertical lengthening along, the shear plane. A model for the strain in transpression is derived, from which the shape and orientation of the finite strain ellipsoid, and the stretch and rotation of lines can be determined.

Analogue models of transpressive systems
Journal of Structural Geology, 2001This paper presents three series of analogue models of transpressional deformation in a brittle/ductile system: (1) simple transpression, (2) transpression combined with erosion of uplifted areas of the hanging wall above the deformation front, and (3) transpression combined with erosion of the hanging wall and sedimentation at the foot of uplifted ...

Strain partitioning in transpression zones
Journal of Structural Geology, 1995Abstract Transprcssional strain acting upon structurally anisotropic rocks can be partitioned into separate deformational domains of pure shear and simple shear. This contrasts with homogeneous transpression in which both the pure shear and the simple shear strain components are uniformly distributed across the zone of deformation.

Incremental pluton emplacement during inclined transpression
Tectonophysics, 2014Abstract Multidisciplinary investigations suggest that many igneous plutons were assembled incrementally, through emplacement of discrete magma batches. Internal pluton contacts between different units can be remarkably cryptic and/or complex in nature.

Oblique simple shear in transpression zones
Geological Society, London, Special Publications, 1998Abstract A mathematical and conceptual framework is presented for extending existing models of transpression and transtension to consider vertical and oblique displacements of the deformation zone bounding blocks. This allows transpression and transtension to be considered in terms of the interplay between four biaxial ‘end-member’ strain ...

Transpression, orogenic float, and lithospheric balance
Geology, 1990In contractional orogens, a throughgoing basal-detachment system at middle to lower crustal levels or conceivably in the upper mantle detaches the entire crustal section from the underlying lithosphere. The decollement system connects transcurrent faults and coeval thrust belts and allows their motions to be viewed as the resolved components of a ...

Triclinic transpression zones with inclined extrusion
Journal of Structural Geology, 2009Data from natural transpressional shear zones reveal a large range of lineation orientations that can spread along complete girdles. One possible way to account for such a type of fabrics is variation in the extrusion direction. This work presents a new theoretical model of oblique transpression with inclined extrusion.

Post collisional transpressive tectonics in northern Sardinia (Italy)
Journal of the Virtual Explorer, 2005The aim of this work is to review and synthetize the geological and structural analysis performed in the Variscan Basement of Northern Sardinian during the last ten years and to add new preliminary data on the Anglona-SW Gallura area. A transpressive crustal- scale deformation (D2), is documented in the Variscan Basement of northern Sardinia.
