英文摘要	The texture and formation age of the Irtysh collision belt between the Altaid terrane and Sawuer oceanic island arc is one of the hottest topics surrounding the tectonic evolution of the Central Asian Orogenic Belt. In this contribution, we report new results of the texture and formation age of the eastern Irtysh collision belt. The results reveal the following evidence; 1) the eastern Irtysh collision belt is consisted of four NW-NNW-trend vertical ductile deformation zones with an asymmetrical fan-like texture in transverse profiles and the strain pattern of apparent constriction and plane strain; 2) the ductile foliation zones have macroscopic to microscopic symmetric structures with cream-cake' style, and were possibly related to coaxial compression caused by the collision between the Altay terranee and Sawuer arc; and 3) the recrystallization zircons from the granodioritic mylonites and ultramylonite from the Yuleken and Laoshankou ductile deformation zone have a similar U-Pb ages of approximately 360Ma. This indicates that the Sawuer island arc had been collided with the Altay terrane in the Early Carboniferous at approximately 360Ma in the Kalaxiangar area.
