| 摘 要： | 扎河坝地区蛇绿岩带属扎河坝—阿尔曼太蛇绿岩带之组成部分，主要由无序的蛇纹岩、变辉长岩、变辉绿岩及少量变质基性火山岩、硅质岩构成其主体。常见外来混杂岩块。据其组合特征可分为蛇绿岩、混杂岩两亚带。经初步研究认为：蛇绿岩为残留洋壳的一部分，其形成时代为奥陶纪—志留纪。加里东晚期洋壳发生转化，至泥盆纪发育一套中基性海相沟弧型火山岩组合。因此，该带及其北部至额尔齐斯带南缘地区，应为西伯利亚板块华力西增生带。

| Abstract: | The ophiolite zones in Zaheba region belong to Zaheba-Aermantai ophiplite belt and consist of non-stratified serpentinite, metugabbro, epidiabaSe, meta-basic volcanic rock,siliceous rock and exotic block. The zones can be divided into an ophiolite subzone and a melange subzone based on their constituting characteristics. The ophiolite formed in Ordovician-Silurian Period. The volcanic arc formed directly on the ophiolite(oceanic cruSt)in Devonian period,and is considered as a Variscan accretionary arc belt in this paper. |
