Palaeobiogeographic affiliation of Cambrian faunas in the Qaidam basin and China' other areas

摘要

Firstly, the authors contrast the Cambrian genera of trilobites, graptolites and brachiopods in the Qaidam Basin with those in other areas of China: the Tarim Basin, the Junggar Basin, the Shaanxi-Gansu-Ningxia (Shaanganning) area, North China and South China. Secondly, on the basis of the calculation of the Otsuka similarity coefficient, they make a Q-cluster analysis. Lastly, they fivide the Palaeobiogeographical provinces and subprovinces, and solve the problem of what in the Cambrian Palaelbiogeography of the Qaidam Basin belongs to which province and subprovince.
