TL;DR: In this article, the geometric consequences of modelling deformation histories involving pure shear, simple shear and inhomogeneous inhomogeneities are reviewed and a model is required that provides a solution to boundary discontinuities associated with bulk shortening and which can accomodate the heterogeneous and anastomosing nature of strain in rocks.

TL;DR: In this paper, six stages of crenulation cleavage development during a single deformation event (D2) can be recognized in both matrix and porphyroblast inclusion trails in the Robertson River Formation, N.E. Australia.

TL;DR: In regional metamorphic rocks, the partitioning of deformation into progressive shearing and progressive shortening components results in strain and strain-rate gradients across the boundaries between the partitioned zones as mentioned in this paper.

TL;DR: In this article, the authors demonstrate the prominent role of reactivation of old foliations during subsegmental deformation by using the orientation of early foliations and stretching lineations within strain shadows or inclusion trails, even where these structures have been rotated or obliterated'in the matrix.

TL;DR: The structural geometry of a mylonite zone (the Woodroffe thrust) and the country rock in its immediate vicinity is described in this article, where it is demonstrated that the fold axes formed initially at approximately 90° to mineral elongation but rotated with increase in strain towards it.
