Abstract: The tectonic reconstruction of the continental masses in China during Cambrian time has been made on the basis of the palaeomagnetic data available and plate tectonic information. The author contends that during this period there existed three oceans and four continents on the Earth. The Yangtze, Tarim and Qaidam landmasses in China are assigned to the Gondwana continental domain. The North China landmass is sandwiched between Gondwana and Laurasia continents. The positions of the North China and Yangtze landmasses respectively in the northern and southern parts at that time turned out opposite to each other at present. The Qinling-Qilian ancient oceanic basin was then a longitudinal ocean near the equator in the southern hemisphere.
