1975年5月27日,我国九名男女登山运动员再次登上了世界最高峰——珠穆朗玛峰。随同中国登山队活动的中国科学院珠穆朗玛峰科学考察队,再次对珠穆朗玛峰北坡进行了科学考察,获得了很多珍贵的资料.其中从珠穆朗玛峰(以下简称珠峰)北坡7029—8840米的四十五个不同高度上所获得的岩石标本,为讨论珠峰地层单位的划分、时代及对比提供了较充分的根据。此外,在考察区北部分布的石炭、二叠系中,首次发现了我们称为岡瓦纳相地层的冰海相沉积及与之伴生的Stepanoviella动物群,并再次发现了保存较好的舌羊齿植物。 本文除对珠峰北坡分布的古生界及其以下一段地层进行系统的描述外,着重对浅变质的震旦—寒武系和岡瓦纳相地层作了讨论.初步认为,珠峰北坡地区与喜马拉雅其它地区、巴基斯坦盐岭以及南亚次大陆都具有地质发展上的密切联系,并推断喜马拉雅山应属于岡瓦纳南亚(印度板块)或岡瓦纳古大陆的一个组成部分.
May 27, 1975, China’s nine men and women mountaineers once again boarded the world’s highest peak - Mount Everest. Accompanied by the Chinese mountaineering activities of the Chinese Academy of Sciences Everest scientific expedition, once again on the northern slope of Everest conducted a scientific investigation, access to a lot of valuable information .Among them from Mount Qomolangma (hereinafter referred to Everest) on the north slope of 7029-8840 m four Fifteen rock specimens obtained at different altitudes provide more sufficient basis for discussing the division, age and contrast of units in Mount Everest. In addition, in the Carboniferous and Permian distributed in the northern part of the study area, the ice-sea facies and associated Stepanoviella fauna that we call the Gondwana Formation were first discovered. Once again, the well-preserved tongue sheep Tooth plant. In addition to the systematical description of the Paleozoic and its following strata distributed on the north slope of Mount Everest, this paper mainly discusses the shallow metamorphic Sinian-Cambrian and Gondwana stratigraphy. It is preliminarily believed that Mount Everest North The slope region is closely associated with the rest of the Himalayas, Pakistan’s salt flats and the subcontinent of South Asia, and concludes that the Himalayas should be part of the Gondwanaland (Indian Plate) or Gondwanaland.
