     After much more field observe, analyse, experiment and integration research, thinking of the 1 ： 250 000 region geological survey data and the other researcher work results, study in the characteristic of tectonic-lithofacies Paleogeography during Early-Middle Permian in the west Kunlun and adjacent areas and discuss the mechanism of formation. The paper suggest that the normal ocean trench-arc-basin system developed in this areas and in this time, from north to south,that are Tarim continent plate, west Kunlun behind arc rift valley basin, west Kunlun middle magma arc, west Kunlun south accretionary wedge, Yulongtage-Bayankala ocean basin and Tianshuihai continent plate. Besides this, continental facies, continental-ocean facies, coastal-shallow sea,bathyal-deep sea facies were developed. Vertical direction was sea advance and regression cycles, magma strong activity, tectonic paleogeography eviroment complex. Yulongtage-Bayankala ocean basin developed strongly and be biggest in this time. In this later period,the Hualixi movment leading to the plates grew exacerbation and Yulongtage-Bayankala ocean basin plate subduction northward, subsequently, the west Kunlun behind arc rift valley basin had been formed, dynamics mechanism from strongly expanded to convergenced. It has much more significance for stratum, geological evolution and mineral deposit explore that research in this tectonic-lithofacies paleogeography in this area and this time.
