| 摘 要： | 青海天峻南山蛇绿岩为本次1:5万区调中首次发现。从其地质特征、岩石化学及地球化学特征反映出陆内裂谷扩张的早石炭世小洋盆构造环境。它的发现对于重新认识宗务隆造山带的地质属性、地球动力学机制,与祁连造山带、柴达木地块的构造关系以及研究古特提斯洋演化提供了新的依据。

| Abstract: | Tianjunnanshan ophiolite was firstly found in 1: 50000 regional geologicalsurvey. According to the geological characteristics, petrochemistry and geochemistry, theophiolite would be formed in a Early Carboniferous minor oceanic basin of intracontinentalrift type. It provides a new basis to recognize the geological attribute and geodynamicmechanism of Zongwulong orogenic belt, tectonic relationship among Zongwulong orogenicbelt, Qilian orogenic belt and Qaidam block, and furthermore to study Tethys oceanevolution. |
