在野外实地考察和追索的基础上,详细厘定了特提斯喜马拉雅带中段晚古生代以来火山岩的分布特点和迁移规律。结果表明,在特提斯喜马拉雅带中段晚古生代以来的地层系统中,从二叠纪→三叠纪→侏罗纪→白垩纪,共有11个层位含规模不等的火山岩,它们以透镜体、薄夹层或以块状玄武岩、玄武质安山岩等形式产出于不同地层系统中;从二叠纪→早中三叠世→晚三叠世→侏罗纪和白垩纪,具有由西向东、从南→北→南→北的迁移规律。这些火山活动的发现和厘定,对填补特提斯喜马拉雅带火山岩研究的空白,了解陆下岩石圈地幔和软流圈地幔之间的相互作用和新特提斯洋盆的形成演化都具有一定的指示意义。
Based on field investigation and recourse in the field, the distribution and migration of volcanic rocks have been determined in detail since the Late Palaeozoic in the middle Tethys Himalayan zone. The results show that in the stratigraphic system since the Late Paleozoic in the middle Tethys Himalaya belt, there are 11 volcanic rocks ranging in scale from Permian to Triassic to Jurassic to Cretaceous, , Thin interbed or in the form of massive basalt, basaltic andesite and other forms of production in different stratigraphic systems; From the Permian → Early Middle Triassic → Late Triassic → Jurassic and Cretaceous, with west to east, From South → North → South → North migration rules. The discovery and determination of these volcanic activities are of great significance for filling in the blank of the Tethyan Himalayan volcanic study, understanding the interaction between the lithospheric mantle and the asthenosphere mantle, and the formation and evolution of the Neo-Tethys. Indicate the meaning.
