Abstract

According to the statistical analysis of isotopic dating data of the basement of the Qiangtang Basin and the review of its geotectonic properties from literatures by different scholars, we reached a conclusion that the metamorphic basement, which is exposed in the central uplift zone, has gone through the Pan African orogeny, and thus the evolutionary process of the Qiangtang block was influenced by the Gondwana paleo-land. The result is helpful to the understanding of the geotectonic background of the region and to the study of Paleotethyan suture zone.
