RELATIONSHIP BETWEEN THE COMPOSITION OF SEDIMENTARY COVER FORMATION AND SPACE-TIME EVOLUTION OF TECTONIC PALEOGEOGRAPHY IN LIAONING PROVINCE

Guided by the theory of plate tectonics, the dynamic processes of continental block divergence, convergence, collision and orogeny are studied to divide the tectonic evolution stage of continental blocks in Liaoning Province. This region is composed of multiple paleogeographic tectonic units, including two first-order units (Jiao-Liao landmass and JinJi-Liao landmass), three secondary-order units (Liaodong intracontinent, Yanliao rift and Yanliao intracontinent), eleven third-order units and fourteen fourth-order units. The relationship between the comosition of sedimentary rock formation and the time and space structural evolution of tectonic paleogeographic units provides basic geological data for the research of the tectonic evolution environment in Liaoning Province.
