Types of ruptures and their arrangement. In Europe it is possible to see, how prevailing types of ruptures from one area to another vary. The main types of ruptures the following:

Cross-section breaks. In the northwest, the southwest and the south (the Great Britain, Iberian peninsula, Turkey) Europe is limited by cross-section breaks. In internal areas of continent this type of breaks has smaller value. Concerning some cross-section breaks it is supposed, but it is not proved, that it is possible to consider them transformnymi. The majority of them developed as dumps, and on them there were considerable vertical displacement (for example, on break Grejt-Glen).

The Ruptures connected with development of flexures. The important tectonic elements of Europe are deflections of the big horizontal sizes. They are typical for regional zones and internal areas dokembrijskoj the East European platform.

Nadvigi. The tectonics okrainnyh and internal parts alpid, kaledonid and uralid is characterised by development nadvigov which represent as well one of tectonic elements of structure of not folded sedimentary cover.

Vertical ruptures. Vertical ruptures as a whole prevail; often they have razdvigovyj character and open to a surface in the form of a wedge. Special type of vertical ruptures - threefold joints with assumed or established mantijnymi streams (' plumes ') which active streams, under the assumption, develop in continental tafrogennye depressions, and dying off streams form initial structures of large pools osadkonakoplenija. As examples of a threefold joint valleys (grabeny) the Top and the Bottom Rhine and the Giessen depression (graben) can serve.

The Systems of ruptures having various orientation, are often imposed one on another. Are observed or the orthogonal cracks parallel to the prevailing regional field of pressure, or ruptures of diagonal directions more often. These various types of systems of ruptures are not connected with any certain floors of earth crust (though orthogonal ruptures are especially typical for a structural floor in which occurs skladkoobrazovanie) and depend on the mechanism of tectonic movements.

If structures grabenov were formed over zones having chopped off in the base orientation of ruptures submits to a field of pressure in the base.

The Difficult systems consisting of many pairs of ruptures, are observed more often in deep erodirovannyh platform areas.
