| 摘 要： | Based on the data about sedimentary facies and palaeogeography, this paper proves the existence of the Cathaysia (the part in eastern Zhejiang and northern Fujian, the same hereinafter) and makes a survey about its palaeogeography since Sinian Period. It also discusses the evolution of the tectonic environment of this region during Phanerozoic Eon, according to the features such as the composition of sandstones derived from the old land and alkalinity of volcanic rocks and so on. Continuous uplifting was maintained in Cathaysia during Sinian Period and Paleozoic Era, typically with no significant tectono-magmatic activity being observed. Its northwestern margin belongs to the type of passive continental margin during the middle and late phase of Caledonian Cycle. It showed the characteristics of a steady continent in late Paleozoic era, but was turned quickly into an active continental margin after the middle Jurassic period.
