摘要
Based on the studies of geochemistry,zircon LA-ICP-MS U-Pb dating and the test of the Lu-Hf isotopic composition,this paper mainly discusses the petrogenesis,magma source,tectonic setting of the Linglong granite. It is suggested that during the early Yanshan,the subduction of Pacific plate leaded to the extension of the continental arc and the lithospheric thinning,directly resulting in the mantle magma underplating which provided thermal power and the old and mafic lower crust partly melting to form the Linglong granite.
