摘　　要：现今分布于中朝、塔里木古陆与西伯利亚古陆之间的古亚洲构造域,既存在于前中生代,也存在于中新生代.古亚洲构造域不能等同于古亚洲洋及其构造域.作为古亚洲构造域一部分的古亚洲洋开始于晚寒武世—奥陶纪,结束于中三叠世.古太平洋及其构造域形成于晚古生代,印支期后,成为滨太平洋构造域.在晚三叠世—侏罗纪时期与古亚洲构造域并存,形成两个构造域的板内造山带、局部盆山构造和东北高原.早白垩世形成以滨太平洋构造域为主体的北北东向盆山体系.The Paleo-Asia Tectonic Domain between the Sino-Korea, Tarim and Siberia old landmasses presented not only in Pre-Mesozoic, but also in Mesozoic-Cenozoic period. The Paleo-Asia Tectonic Domain does not equal to the Paleo- Asian Ocean and corresponding tectonic domain. Being a part of the Paleo-Aisa Tectonic Domain, the Paleo-Asian Ocean appeared in Late Cambrian-Ordovician, and ended in Middle Triassic. The Paleo-Pacific Ocean and its tectonic domain formed in Late Paleozoie, and transformed into the Marginal Pacific Tectonic Domain in Post-Indosinian epoch. It coexisted with the Paleo-Asia Tectonic Domain, to form the intraplate orogenic belt, partial basin-and-mountain structure and northeastern highlands in the two tectonic domains during the Late Triassic-Jurassic epoch. The NNE-striking basin- and-mountain system, dominated by the Marginal Pacific Tectonic Domain, finally formed in Early Cretaceous.
