In geology, tectonostratigraphy is stratigraphy that refers either to rock sequences in which large-scale layering is caused by the stacking of thrust sheets, or nappes, in areas of thrust tectonics or to the effects of tectonics on lithostratigraphy.
The tectonostratigraphy of the Moldanubian Zone sensu stricto is divided into three main units: At the top the Gföhl unit, a stack of south-vergent crystalline nappes. It consists mostly of rocks of high metamorphic grade (up to amphibolite or granulite facies). These can be metamorphic sediments but also orthogneisses.

Engraving from William Smith's monograph on identifying strata based on fossils. Catholic priest Nicholas Steno established the theoretical basis for stratigraphy when he introduced the law of superposition, the principle of original horizontality and the principle of lateral continuity in a 1669 work on the fossilization of organic remains in layers of sediment.
The High Karst Unit of the External Dinarides is a tectonic unit established by French geologists, so-called Aubouin's group, as reviewed in a recent scientific literature. [3]
