The terms "Cathaysia", "Cathaysialand" and "Cathaysia Terrane" have been used by various authors for different continental blocks or terranes and assemblages thereof. During the Devonian, the South China and Indochina continents had separated from Gondwana and they collided during the Carboniferous to finally form a superterrane in the Permian. "Cathaysia" has been used for some or all of the constellations involved in this tectonic journey.[1] For example, in Шаблон:Harvnb South China formed from the amalgamation of the "Yangtse and Cathaysia Blocks", whilst Шаблон:Harvnb groups North China, South China, and Indochina into the "Cathaysian terranes".[2]
Cathaysia, sensu Scotese, are a few of the almost 70 microcontinents that are involved in the formation of Asia.[3] Furthermore, Cathaysia, both sensu Scotese and Li et al., is grouped among the "lonely wanderers" of Шаблон:Harvnb — smaller continents whose position varies dramatically between plate reconstructions.[4]
Paleoclimate
During the Permian Cathaysia/South China was located near the Equator and within the Paleo-Tethys Ocean together with the North China continent and these two small continents share what is often called the "Cathaysian floras and faunas" (in contrast to the "Gondwanan floras and faunas").[5]
As North and South China collided during the Late Triassic the Qinling Ocean closed.[6]
South China was covered with coal forests formed by seed ferns of the order Callistophytales, whilst tree-like Lycopodiophytes survived into the Permian.
