    • Abstract
  • The Xijir Ulan tectonic melange belt is the western part of Xijr Ulan-Jinshajiang sutural zone,because study in low degree in the past,it is still indefinite.After 1:250 000 regional surveys,study shows that the belt is comlex.It consists of basement,seabeach-sandstone,gabbro(diabase)dike swarm wall group,ophilite,silicalite,limestone(kop),flysch,and molasses.The ophiolite partly formed ocean ridge,mainly formed in an ocean island.Confined the Xijir Ulan tectonic melange belt consists of a sierise blocks seprated by thrust towards south.The evolution progress of the The Xijir Ulan tectonic melange belt is summarized primarily.
