| 摘 要： | 对位于青海省玛沁县境内的德尔尼蛇绿岩进行了报道，并使用地球化学方法进行了确认和判别。研究表明，其岩石组合相对简单，由玄武岩、辉长岩和蛇纹岩３个单元组成。玄武岩微量元素判别表明，该蛇绿岩形成于典型洋脊环境，属于西地中海型岩石圈残片，是青藏高原目前发现的最北端的特提斯蛇绿岩，向东可能与南秦岭勉略带相连

| Abstract: | Derni Ophiolite is exposed in Maxin County, Qinghai Province. It has a simple but complete rock formation:Lavas Massive gabbros Metaperidotites. Geochemical study shows characteristics of typical N MORB. The ophiolite may be grouped into west Mediterranean type and thus, Derni Ophiolite is regarded as relics of East Tethys. To be important, it is the northernmost ophiolite of this kind. |
