Abstract: The Fuhai area of north Xinjiang is situated in the convergent zone between Siberia Plate and Kazakstan Plate. This area was in an island arc and retroarc basin environment so that its structure activity is violent. There exists many kinds of depositional basins in the Upper Palaeozoic, such as oceanic basin, remnant oceanic basin, island-arc basin, bycontinentalarc basin, intracontinental basin, and so on. There are all kinds of lithofacies: deep-sea,shallow sea, coastal sea, deltaic and fluvial, lacustrine, and swamp facoes. Lots of mixed subfacies zones cause the complex distribution of factes zones. Because of the seawater's withdrawal, continental factes replaced marine factes completely in the Late Carboniferous. Resultantly,the Paleoclimate appeared remarkably different. The Palaeozoic deposition ceased by the end of Early Permian.
