Abstract
Tuzituoyila fault belt,situated in the northeast margin of the JunggarBasin,is primarily made up of northeast dipping thrusts.Its structural cha-racteristics is very similar to Karamay fault belt,and possesses of 3 terra-ces descending step by step from edge to the centre of the basin.This faultbelt was mainly moved in the end of the Paleozoic to the Jurassic.So theforeland depression connecting with the belt is primerily filled with Triassic-Jurassic and Upper Permian sediments.Upper Permian is considered as amajor source rock,Upper Triassic and Sangonghe Formation of the LowerJurassic may be secondary.Tuzituoyila fault belt may be provided withconditions for forming a complex oil and gas accumulation zone whichmay contain various kinds of oil pools such as fault block,fault-lithologicaland basement rock pools,etc.
