Caledonian granitic magma intrusion the trend of the times in support of this view [3]. Late Paleozoic PaleoTethys cracking is, subduction zone to migrate to near Kangxiwar fault zone subduction direction by the SouthWest to North East and West Kunlun with the Late Paleozoic magmatic arc (Queensland multiphase magmatic arc ) [4], the Kusi La Fu Dragon regions in postarc subduction under the influence of the development of backarc rift of the Late Paleozoic (ie Chur, oytag, Liang rift trough). With the demise of the PaleoTethys, Kusi La Fu Long Late Paleozoic rift basin closed at the end of the Permian. Triassic in this area in the uplift and denudation, missing deposition. Jurassic mountain basin phase sandwiched between swamp facies. To the end of the Cretaceous and early Tertiary early, due to the role of NeoTethys rift suffered a transgression, forming a shallow marine to lacustrine sedimentary rocks. Himalayan orogeny, the NeoTethys closed, the rise of the Tibetan Plateau, the basin tectonic sharp distinction, causing largescale overthrusting and strikeslip of the the West Kunlun front of this area, the formation of iron in grams over the nappe and other structures, tectonic framework laid today.
