柴达木盆地石炭纪古生物地理归属研究

柴达木盆地石炭纪的Ｔｉｎｇ类，珊瑚和腕足动物的代表属与中国其它代表地区－塔里木盆地，准噶尔盆地，陕甘宁地区，华北地区，华南地区，西藏北部地区可以进行对比，在计算大Ｚｏｎｇ相似系数的基础上，进行Ｑ型聚类分析，得出古生物地理分区结果，则解决柴达木盆地石炭纪古生物地理归属问题，研究结果表明，早石炭世可划分为：柴达木－华南－陕甘宁生物区；塔里木－藏北生物区和准噶尔生物区，柴达木属于柴达木－华南生物亚区，晚

PALAEOBIOGEOGRAPHIC AFFILIATION OF CARBONIFEROUS FAUNAS OF THE QAIDAM BASIN,CHINA

By comparing the Carboniferous genera of fusulinids,corals and brachiopods in the Qaidam Basin with those in other regions of China Tarim Basin,Junggar Basin,Shaanxi Gansu Ningxia(ShaanGanNing)area,North China,South China and North Tibet, the Otsuka similarity coefficient and Q cluster analyses were conducted for those faunas. On the basis of the quantitative analyses, the palaeobiogeographical provinces and subprovinces are delimitated for Carboniferous faunas in China. In the Early Carboniferous,China can be divided into the Qaidam South China ShaanGanNing province,Tarim North Tibet province and Junggar province.The Qaidam Basin belongs to the Qaidam South China subprovince.In the Late Carboniferous,China can be divided into the Qaidam,South China North China,ShaanGanNing Tarim province,North Tibet province and Junggar province.The Qaidam Basin still belongs to the Qaidam South China subprovince.
