中国科学院西藏综合科学考察队地层组,于1966—1968年对西藏南部聂拉木县亚来—赖西的石炭纪地层进行了初步研究(章炳高,1974)。本文根据室内分析和野外观察,进一步对该地区石炭系剖面的岩石地层进行了探讨。石炭系的观察厚度达2000米,其岩石组合类型并不很复杂。考虑到各层位岩性的代表性,共采集了43个层号的标本进行岩石学研究,包括:显微镜下岩石薄片的观察(43块标本);粘土质岩(16块标本)、砂质岩(17块标本)及碳酸盐岩(4块标本)的化学分析和
Preliminary study on the Carboniferous strata in Asia-Laiisi in Nyalam County, southern Tibet, from 1966 to 1968 (Zhang Binggao, 1974). Based on the indoor analysis and field observation, this paper further explores the lithostratigraphic of the Carboniferous section in this area. Carboniferous observed thickness of 2,000 meters, the rock type is not very complicated. Considering the representativeness of the lithology of each layer, a total of 43 layers of specimens were collected for petrological studies, including the observation of thin sections of rock under microscope (43 specimens), clay rock (16 specimens), sandy Chemical analysis of rocks (17 specimens) and carbonate rocks (4 specimens)
