本文根据1966—1968年珠穆朗玛峰地区科学考察资料,简要地叙述了包括首次发现的奥陶系、志留系和泥盆系的海相地层及其划分、对比。由奥陶系至老第三系厚达一万米的海相地层,大多是连续沉积,所含化石非常丰富,有二十多个门类。有些门类在珠穆朗玛峰地区或在喜马拉雅地区都是首次发现。珠穆朗玛峰地区南部和北部地层发育情况有明显差异:南部地层较全,从奥陶系到老第三系,发育情况类似干一般所说的地台型沉积;北部只见到石炭、二迭系和中生界,发育情况类似于一般所说的地槽型沉积。
Based on the data from the Everest survey from 1966 to 1968, this paper briefly describes the marine strata, including the Ordovician, Silurian and Devonian marine strata, and their division and comparison. From the Ordovician to the old Tertiary up to 10,000 meters thick marine strata, mostly continuous deposition, contains very rich fossils, there are more than 20 categories. Some categories are found for the first time in the Everest region or in the Himalayas. There are obvious differences in the development of the southern and northern Qomolangma strata: the southern strata are quite complete, ranging from the Ordovician to the Tertiary Tertiary whose development is similar to that of the so-called terraces. In the north, only the Carboniferous and Permian And Mesozoic, the development is similar to what is commonly referred to as geosyncline deposition.
