| 摘 要： | 在新疆阿牙克库木湖幅1：25万区域地质调查中，于东昆仑祁漫塔格山南缘黑山新发现的蛇绿岩主要由堆晶杂岩和大洋拉斑玄武岩残片组成。其具有构造变形弱，蛇绿岩保留厚度较小的特点。拉斑玄武岩具低钾、低钛、富镁，轻、重稀土分馏不明显，大离子亲石元素正常—弱富集、高场强元素弱—强烈富集的特征。综合研究得出黑山蛇绿岩形成于南华—奥陶纪，构造就位于志留纪—早中泥盆世。

| Abstract: | Regionally geological survey at 1:250,000 in the Ayakekumu lake area in SinKiang has revealed that the ophiolite, new dicovered in Heishan mountain of the south margin of Qimantageshan, eastern Kunlun, mainly consists of cumulus crystal complex and residual oceanic tholeiite, with a little structural deformation and a small thickness of remaining ophiolite. The tholeiite is characterized by low potassium, low titanium, high magnesium, unclear in light and heavy rare earth, normal and little enrichment of large ion lithophile elements, low highenrichment of high field elements. Comprehensive researches have concluded that the Heishan ophiolite was formed in Nanhua Ordovician period and its structural location in Silurian period early Middle Devonian epoch. |
