摘　　要：北天山晚古生代蛇绿岩带的巴音沟蛇绿岩是该带的重要组成部分和典型代表。传统意义的巴音沟蛇绿岩带在区内分南北两支,南支为贝勒克蛇绿岩带,北支为巴音沟蛇绿岩带,分别代表早泥盆世末和早石炭世末的两条不同古洋壳残片。The Bayingou ophiolite belt is important and typical in the late Paleozoie ophiolite zone of the north Tianshan Mountains. In traditional significance, the Bayingou ophiolite belt was divided into the Becquerel belt at the south and the Belek belt, which represent different ancient residual oceanic crusts of the late phase of the Early Devonian and the Early Carboniferous epoch respectively.
