Characteristics of junctions of differently oriented structures in the Altay-Sayan region, as in the Shapshal' tectonic complex

Mechanical heterogeneities of the regional folded complex, intricate junctions and intersections of three different systems of deep fractures, impositions of younger structures onto the arcs of the ancient structural Plan, relics of the still more ancient “subcrustal” fractures, and other complexities, lead to a wide variety of the reactions of different parts of the earth's crust to the over-all tectonic tensions and hence to a highly varied assortment of structural expressions of such tensions, notwithstanding a unity of the genesis of all the deformations. – IGR Staff.
