%X 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 components, which are shown graphically as the four vertices of a ‘strain tetrahedron’. Transpressional and transtensional strains represented by the strain tetrahedron generally display triclinic symmetry, although the end-member biaxial strains are orthorhombic or monoclinic. Deformation in which vertical simple shear dominates over horizontal simple shear gives rise to finite strains that tend towards plane strain. Finite strains caused by deformation involving oblique simple shear are generally orientated non-parallel to all three Cartesian reference axes.
