The Huangshaqiao uranium deposit is located in the southern part of the Zhuguangshan composite pluton， on the west side of the Chengkou ore concentration area. In this paper，zircon LA- ICP- MS U- Pb dating，Hf isotope and geochemical composition measurements have been carried out for the granite of the Huangshaqiao uranium deposit. The results show that the ages of the medium—coarse grained porphyritic Biotite granite and the medium—fine grained porphyritic Biotite granite are 152.8±1.1 Ma and 154.1±1.4 Ma，respectively. The results of element analysis show that the two types of Biotite granites are rich in silicon，alkali，high K2O/Na2O ratio and low CaO/Na2O ratio，both of which have relatively consistent REE and trace distribution curves；They are relatively enriched in large ion lithophile elements Rb and high field strength elements Th，U，and Hf，with significant depletion of elements such as Ba，Nb，and Ti. Both have obvious light and heavy rare earth fractionation characteristics，with rare earth partitioning curves showing a right- dipping pattern and distinct negative Eu anomalies. Both types of Biotite granite have lower εHf（t）values (-15.24～-8.96and-13.60～-9.65)，and their Paleoproterozoic model ages（2171～1778Ma and2063～1821Ma）.Both types of Biotite granites belong to strongly aluminous S- type granites，which are mainly partially melted from clay rich argillaceous Sedimentary rock. Both are products of Yanshanian magmatic activity，formed by low degree partial melting of the crustal source area dominated by the Paleoproterozoic era under the extensional tectonic background caused by the subduction of the Pacific Plate.
