Strain modeling of transpressional and transtensional deformation

of lines and planes can be calculated. These quantities are reftected in the fabrics of deformed rocks ( orientation and intensity of lineations, foliations, etc.) which can be used to qualitatively or quantitatively describe the deformation of both active and ancient transpressional/ transtensional deformation zones. Partitioning of transpressionalj transtensional displacement fields into pure shear-enhanced transpressional/ transtensional domains separated by narrower strike-slip shear zones or faults can be modeled in the kinematic framework presented here, and may be applied to centimeter scale partitioning as well as to partitioning at the scale of plate boundary deformation zones.
