内蒙古月牙山蛇绿岩的岩石学、地球化学特征及其地质意义
Petrological and petrochemical characteristics and geological significance of Yueyas- han ophiolite
摘要
Abstract
Yueyashan ophiolite is located in the Hongliuhe-Xichangjing ophiolite belt in the eastern part of Yueyashan area. Yueyas⁃han ophiolite suite is exposed fairly completely, consisting in upward succession of ultrabasic complex, gabbro, layered basalt and pil⁃low basalt as well as radiolarian siliceous rocks. Petrological, petrochemical and geochemical data show that the main unit in the ophi⁃olite suite originated from mantle source and it is very similar to the modern oceanic crust ophiolite. The plagioclase granite associat⁃ed with ophiolite unit belongs to mantle type oceanic plagioclase granite;in addition, it is a part of the ophiolite. Gabbro and basalt were both formed in a normal mid-ocean ridge (N-MORB) environment.关键词
