the sudetes forms the ne border of the bohemian massif. in detail the sudetes is made up of a series of massifs that are rectangular and rhomboid in plan view. these mountains corresponds to horsts and domes separated by basins, including grabens. the mountains took their present form after the late mesozoic retreat of the seas from the area which left the sudetes subject to denudation for at least 65 million years. this meant that during the late cretaceous and early cenozoic 8 to 4 km of rock was eroded from the top of what is now the sudetes. concurrently with the cenozoic denudation the climate cooled due to the northward drift of europe. the collision between africa and europe has resulted in the deformation and uplift of the sudetes. as such the uplift is related to the contemporary rise of the alps and carpathians. uplift was accomplished by the creation or reactivation of numerous faults leading to a reshaping of the relief by renewed erosion. various "hanging valleys" attest to this uplift. block tectonics has uplifted or sunken crustal blocks. while the late cenozoic uplift has uplifted the sudetes as a whole some grabens precede this uplift.

orogenic uplift is the result of tectonic-plate collisions and results in mountain ranges or a more modest uplift over a large region. perhaps the most extreme form of orogenic uplift is a continental-continental crustal collision. in this process, two continents are sutured together and large mountain ranges are produced. the collision of the indian and eurasian plates is a good example of the extent to which orogenic uplift can reach. heavy thrust faulting (of the indian plate beneath the eurasian plate) and folding are responsible for the suturing together of the two plates. the collision of the indian and eurasian plates not only produced the himalaya but is also responsible for crustal thickening north into siberia. the pamir mountains, tian shan, altai, hindu kush, and other mountain belts are all examples of mountain ranges formed in response to the collision of the indian with the eurasian plate. deformation of continental lithosphere can take place in several possible modes.
