This papermainly describes the stratigraphical distribution, lithological characteristics and palaeontological faunas of the Late Darriwilian to Early Katian (Ordovician) marine red beds from the nine blocks, including five main blocks (Yangtze Craton, SinoKorean Craton, Tarim Craton, Lhasa Block and north slope of Himalaya). Their lithological characteristics (such as red limestones) and palaeontolgical faunas (such as conodont Pygodus serra faunas, P.anserinus faunas and Hamarodus europaeus faunas, Coral Yohophyllum faunas, and Cephalopod Sinoceras chinense faunas) of these marine red beds are very similar or same. The result has an important implication for understanding the relation between China oldland and Gondwanan oldland. Maybe it belonged to the same Gondwanan oldland before. It fully suggests that the China palaeoblocks including Yangtze Craton, SinoKorean Craton and Traim Craton are closely related to the palaeoblocks including Lhasa Block and northern slope of Himalaya on the northern side of Gondwanan oldland. This result has an important significance for understanding the relation between China oldland and Gondwanan oldland. Besides, marine red beds can be subdivided into two groups: shelf red beds (SRB) and oceanic red beds (ORB). The former was deposited mainly from Cambrian to Triassic ages, and the latter was mainly from Cretaceous age to present.
