Abstract：Using sequencestratigraphic study approach to divide Paleozoic of Tarim basin into nine stratigraphic sequences and 27 systems. The system study shows the multiple sedimentary types such as carbonate platform,passive continental margin,cratonic basininterior basin and foreland basin are developed successively from Cambrian to Permian. Taking the plate structure theory as a guide and combining with palaeomagnetic data,we discuss the relationship between the type of sedimentary basin and structural evolution and the reforming role of tectonic action on basin. From movement theory,we interpret the geographic position,nature of plate activity,basin type and sedimentary feature in separate epoch of Paleozoic in Tarim basin. It is considered that Paleozoic Tarim plate came into collision with adjacent plates during drift,which made its drift trail show “S” pattern. Since affected by the nature of plate movement,Tarim basin had different types of basin in different period of Paleozoic:Tarim basin was cratonic basin with discrete margin from Cambrian to Early Ordovician;from the late of Early Ordovician to the late of Early Paleozoic,the oceanic crust in eastern part of Tarim plate (current south part) diminished,forming such structural setup that two different basin types,eastern convergent margin postarc foreland basin and northern passive continental margin basin with discrete margin,coexisted;from Silurian to Devonian,the Tianshan ocean in northern margin of Tarim plate sealed,the Tarim plate came into collision with Kazakhstan plate,forming cratonic basininterior basin;the southwestern margin of Tarim basin in Carboniferous was discrete margin,forming passive continental margin basin;the Tarim basin in Permian was foreland basin.
