Abstract: The magmatic activities of the Yanshan period in North China Craton are an ideal carrier for studying the mechanism of craton destruction. In this paper, the Daqingshan granite was selected for LA-ICP-MS zircon U-Pb dating and geochemical analysis to investigate the rock genesis and its implications for the Mesozoic tectonic-magmatic evolution in the northern margin of the central North China Craton. The results show that the granite consists mainly of phenocryst adamellite, with a zircon U-Pb age of (139±1) Ma (MSWD=0.28, N=12), indicating an early Cretaceous magmatic event. The geochemistry of the genesis indicates that it is highly silicic, alkali-rich, relatively potassium-rich, peraluminous, and magnesium-titanium-phosphorus-calcium poor. The genesis was classified as a highly differentiated type I granite of peraluminous for the results of NK/A, saturation temperature of zircon and the value of P₂O₅, Zr and FeO^T. The granite is enriched in large ion lithophile elements (Rb, Th, K) and depleted in high field-strength elements (Ba, Sr, P, Ti). The total rare earth element contents are low (ΣREE ranges from 84.5×10^-6 to 216.0×10^-6), with a strong fractionation between light and heavy rare earth elements and significant negative Eu anomalies (δEu=0.08~0.56), showing a four-group pattern. The genesis exhibits obvious characteristics of crustal source and intrusion age coincides with the peak period of magmatic activity in the North China Craton, representing a shallow magma response to craton thinning, closely related to the retreat of the ancient Pacific plate.
