Flora of Palaeozoic coal balls of China
View through CrossRef
The geographic distribution of coal balls of China and their stratigraphic range are very wide. Fossil plants in coal balls are abundant Floras of coal balls of Jingyuan Gansu contain the same content as those of the Hauptfloz coal of Ruhr and the Kokfloz coal of Ostrau (Namur C) in Europe. Coal balls of Shanxi and Shandong (P1) are abundant and highly diversified with flourished Cathaysian flora, while in the coal balls of Shuicheng, Guizhou (the top of Upper Permian) the Cathaysian flora somewhat declines and shows less in diversification. Some Mesozoic coloured elements have also been observed.
