摘要
LA-ICP-MS zircon U-Pb dating and geochemical data for the Mesozoic volcanic rocks from the Lingquan Basin in Manzhouli area were presented in order to constrain their petrogenesis and the regional tectonic evolution. Combined with spacial distribution of the Mesozoic volcanic rocks, it is suggested that the formations of the Middle Jurassic and early stage of the Early Cretaceous volcanic rocks could be related to the evolution of the Mongol-Okhotsk orogen, whereas the formation of the latest Early Cretaceous bimodal volcanic rocks should be related to subduction of the Paleo-Pacific Plate beneath the Eurasian continent.
