摘要
大草滩韧性剪切带岩石变形特征明显，有从强到弱三个程度不同的变形带，它是从晚石炭世初至晚石炭世末期发展起来的，是准噶尔板块和塔里木板块相互作用的结果．
The character of the rock deformation in Dacaotan ductile shear zone is obvious. Thereare three deformation zones. Dacootan ductile shear zone developed during the late Carbonif-erous period and it's the result of the mutual action between Tarim plate and Junggar plate.
