摘　　要：蛇绿岩是具有特定成分的镁铁-超镁铁岩石组合。本文通过对达尔布特断裂西南部布尔克斯台一带晚古生代蛇绿岩岩石地球化学分析,初步判断本区晚古生代蛇绿岩具备岛弧火山岩特征,该蛇绿岩应属于SSZ型,形成于未成熟岛弧的弧后盆地环境中。Ophiolite is a mafic ultramafic rock association with specific composition.Based on the geochemical analysis of the late Paleozoic Ophiolites in the buerkestai area,southwest of the darbute fault,it is preliminarily determined that the late Paleozoic Ophiolites in this area have the characteristics of island arc volcanic rocks.The ophiolites should belong to SSZ type and formed in the back arc basin environment of immature island arc.
