摘要
South Tianshan orogen between Tarim and middle Tianshan has undergone complicate tectonic evolution，especially，the fore-arc accretion during the subduction of the oceanic crust of the ancient south Tianshan ocean under the middle Tianshan volcanic arc. There are various understandings about the beginning time of south Tianshan collision orogeny. Analyzing from the geological data, esp., radiolarian, ophiolite, blueschist，volcanic arc and foreland basin deposits, the beginning time of collision in south Tianshan is P3-T1.oft-com:office:office" />
