Further study of the Carboniferous-Permian Boundary in Yunnan and its correlation;

Biostratigraphy and sedimentary environments of Carboniferous-Permian boundary section of Yutangzhai,Yongde County,Western Yunnan;

Based on the case study on the platform-facies carbonate rocks of the Carboniferous-Permian boundary section being well developed and outcropped in Xikou,Zhen an County,Shaanxi Province,China,this paper probes into the carbonate diagenesis controlled by glacioeustatic sea-level changes and its different patterns.

Conodonts from the Permian-Triassic boundary beds at the Huangzhishan Section, Zhejiang are systematically studied for the first time, with a total of 16 species assigned to 2 genera.

The carbon isotopes of the marine carbonate rocks of the permian strata and Permian-Triassic boundary were analyzed in Guangyuan and Chongqing of Sichuan province, and in Luodian of Guizhou province.

The study on Permian_Triassic boundary (PTB) in South China has been one of the most important topics among geologists all over the world.

Based on detailed investigation of the sedimentology and conodont faunas on the Permian_Triassic boundary strata of the Meishan section, Zhejiang Province, South China, a new paleoecological model about two important genera Hindeodus and Clarkina (or Neogondolella ) is proposed.

This paper describeds the conodonts of 10 genera referred to 29 species and subspecies from mid-Carboniferous boundary strata of South Guizhou and North Guangxi.

The international definition on the mid-Carboniferous boundary and the Namurian palyno- logical zonations of West Europe and Donetz Basin are briefly introduced.
