The Kalaqin area, located in the northern Yanshan tectonic belt, is considered to be an ideal area for understanding tectonic evolution of the Yanshan tectonic belt due to the presence of several phases of Late Paleozoic-Mesozoic magmatic activities and deformation events. Based on dating of the igneous rocks and studying of the deformation events, combining with the regional geological data, tectonic evolution history in the Yanshan tectonic belt during Late Paleozoic and Mesozoic was deduced comprehensively in this study. It shows that the Yanshan tectonic belt was in an active continental margin setting with arc-related magmatism during the latest Early Carboniferous and Early Permian due to the subduction of the Paleo-Asian ocean. The closure of Paleo-Asian ocean along the Solonker suture in Middle Permian resulted in foreland shortening deformation zone and appearance of magmatic quiescent period correspondently in the Yanshan tectonic belt. The belt was followed by four periods of extension-related magmatic activities in Late Permian-Triassic, Middle Jurassic, Late Jurassic and Early Cretaceous respectively. Each of the magmatic events was interrupted by a quiescent period of magmatism related to a compressive event happening in Early Jurassic, Early Late Jurassic and Early Cretaceous respectively. These phenomena suggest that there exists coupling relation between the magmatic activities and tectonic evolution. Each of the intraplate magmatic events happened under the extensional setting whereas every compressive event corresponds to the magmatic quiescent period in the Yanshan tectonic belt.
