Description: This book describes the widely occurring manifestation of superposed simple shear deformation in the form of highly varied plications, plicate-disjunctive and disjunctive tectonic structures of all possible dimensions. Mathematical laws of distribution of the displaced elements of the layers, which predetermine the morphological characteristics of the various tectonic structures found in zones of simple shear, are highlighted. The mechanisms which control the morphology of structures which interfere in such zones are examined. Relegation of that part of such structures to the category of traditionally discussed nappe-folds is established. The possibility of construction of three-dimensional models of structures of complex folded systems resulting from interferences in polyphase folded zones through mathematical modelling, using the EVM computer, is explored. It appears that the accuracy of geological mapping and the extrapolation of the structural relations observed on the surface to deeper levels can be considerably improved through the use of such models. Some problems of the dynamics of processes of structural formations in the earth's crust are also discussed. The indispensability of calculations while studying these processes of movement characteristics in terms of mechanical strain is demonstrated. This book is intended for geologists engaged in geological investigations in regions characterised by the development of highly dislocated formations.
