Western Tianshan is divided into four belts: the northern Tianshan forearc melange belt, the central Tianshan composite magmatic arc belt, the southern Tianshan backarc melange belt and the southern Tianshan Late Paleozoic magmatic arc belt.
从构造角度将西天山分为北天山弧前混杂岩带、中天山复合岩浆弧带、南天山弧后混杂岩带及南天山南缘晚古生代岩浆弧带；并且重建其古生代构造演化史：震旦纪一奥陶纪，古天山－准噶尔洋向南俯冲，在塔里木板块北缘中天山离散地体基底上形成中天山早古生代岩浆弧；志留纪－石炭纪，在中天山早古生代岩浆弧与塔里木板块之间形成南天山弧后盆地，随后该弧后盆地往北俯冲于中天山之下，此时古天山－准噶尔洋继续往南俯冲于中天山之下，从而形成中天山复合岩浆弧带；二叠纪，古天山－准噶尔洋、南天山弧后盆地相继封闭，古天山造山带形成；此后便进入陆内演化阶段；南天山南缘晚古生代岩浆弧则是塔里木板块往北的陆内Ａ型俯冲导致的。
