REGIONAL TECTONIC IMPLICATION OF THE PALEOZOIC STRATIGRAPHIC PALEONTOLOGY INFORMATION IN NORTHEAST CHINA

Through analyzing the Paleozoic stratigraphic paleontology information in Northeast China and its correlation with regional tectonics of the Paleo-Asian Ocean, it is considered that the Paleozoic tectonic evolution of continental block group in the northern Northeast China and adjacent fold belts are parts of the evolution history of Paleo-Asian Oceanic tectonic domain. The small oceanic basins formed after the Late Silurian-Early Devonian have the property of tectonic superposition. The migration and intergrowth of Cathaysia and Angola flora indicate that the collision-collage between Siberian Plate and Sino-Korean Plate is earlier than the Late Carboniferous-Early Permian. The formation of Permian deep-water radiolarian siliceous rocks may be related to the paleo-suture zone-activated aulacogen during the plate convergence.
