Early Cambrian continental reconstructions
@article{Mckerrow1992EarlyCC, title={Early Cambrian continental reconstructions}, author={W. S. Mckerrow and Christopher R. Scotese and Martin D. Brasier}, journal={Journal of the Geological Society}, year={1992}, volume={149}, pages={599 - 606} }
Climatically-related sedimentary facies and faunal distributions have been combined with palaeomagnetic data to make provisional reconstructions of the early Cambrian world. Laurentia, Baltica and Siberia appear to have formed a continental group which rifted apart from each other prior to 600 Ma. The consolidation of much of Gondwana probably occurred (in the Pan-African orogeny) well before the Cambrian, though the assembly of several east Asian terranes is still speculative. The…

SUMMARY
During the Cambrian, two types of continental margins occurred around Gondwana. The eastern margin (Antarctica, Australia and southern South America) was characterized by a narrow…
