///The Haoping and Jinshanmiao granitic plutons occurred in the southern margin of the North China Craton, are the important components of the Huashan complex batholith in Xiongérshan region.Zircon LA-ICP-MS U-Pb dating yields ages of (128.7±1.0) Ma to (129.3±2.4) Ma for Haoping pluton, and of (127.6±1.6) Ma for Jinshanmiao pluton, suggesting that they were all formed in Early Cretaceous. The Lu-Hf isotopes shows that the εHf（t） values of the Haoping pluton range from -10.2 to -13.3, with tDM2 ages between 1.8 Ga and 2.0 Ga, while the εHf（t） values of the Jinshanmiao range from -13.3 to -17.5, with the tDM2 ages of 2.0 Ga to 2.2 Ga,  indicating that these two plutons might be derived from the ancient materials of Taihua Group basement which was reformed by the mantle or the juvenile crust during the long-time geological evolvement.Integration of regional geology, whole-rock geochemistry and geodynamic considerations suggests that the Haoping and Jinshanmiao plutons should be emplaced in the intracontinental extensional environment followed by the end of the collision between the Yangtze and the North China blocks,  which implies that they were formed during the tectonic transition from the Paleo-Tethys subduction-collision system to the Paleo-Pacific regime.
