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 The Terni ophiolite, located in the state of Maqin County, Qinghai Province, was reported and identified and identified using geochemical methods. Research shows that its rock assemblage is relatively simple and consists of three units, basalt, gabbro and serpentinite. The trace elements of basalts show that the ophiolite is formed in a typical ridge environment and belongs to the western Mediterranean lithospheric debris. It is the northernmost Tethyan ophiolite currently found in the Qinghai-Tibet Plateau. It may be associated with the southern Qinling Mianleo Connected
