| 摘 要： | 葫芦河蛇绿岩主要由蚀变橄榄岩、橄榄辉石岩、辉石角闪石岩、层状—块状辉长岩、苏长岩、辉石闪长岩、英云闪长岩、枕状—块状玄武岩、辉绿岩及少量硅质岩、硅质灰岩等组成,形成于震旦纪—早古生代。通过对该蛇绿岩带地质及岩石地球化学特征等进行了论述,认为其形成于近弧的弧后盆地扩张脊环境。提出葫芦河蛇绿岩带属"野马山—木里—拉脊山早古生代结合带"东延组成部分。

| Abstract: | The Huluhe ophiolite is mainly composed of metoamorphic peridotite,olivine pyroxenite,layered and massive gabbro,pyroxenite diorite,tonalite and massive basalt,diabase and thin-bedded chert,chert limestone.its produced from Sinican Period-Early Paleozoic.This paper discusses the feature of geology,lithogeochemical of this ophiolitic belt,so the ophiolite is produced from near the back-arc basin spreading ridge.The Huluhe ophiolite zone includes "Early Paleozoic of Yemashan-Mouli-Lajishan suture zone" a eastward extension. |
