Langshan area widely distributed intermediate-acid magmatic rocks. The existing researches are collectively referred to as Hercynian composite rock mass but lack of accurate dating results (Peng RM, et al., 2007. Li JY, et al., 2009. Chen XF, et al., 2011. Pi QH, et al., 2010). This is the first report southwest Langshan Middle Permian granite of U-Pb age which could provide new evidence for the study with magmatism evolution in Langshan region and tectonic thermal event in the process of Central Asia orogenic, and help understand the age framework of the northern margin of the North China Platform. This research has an important geological significance.
