During the late Mesozoic times, the SE China is characterized by extensive magmatism and mineralization. The widely distributed granitoids with different (I-, Sand A-) types have been inferred to be closely related to the large-scale polymetallic mineralization. The Nanling tungsten-tin polymetallic belt is endowed with considerable mineral resources. The recently discovered Tiantangshan Tin Polymetallic Deposit is located in the eastern area of the Nanling tungsten-tin polymetallic belt. The mineralization of the Tiantangshan Tin Polymetallic Deposit and the petrogenesis of ore-associated intrusions remains enigmatic. In this work, we have investigated two ore-associated intrusions in Tiantangshan Tin Polymetallic Deposit. We present the first detailed SHRIMP zircon U–Pb dating, major and trace element geochemical and Nd isotopic data for these two intrusions. These new data allow us to explore the origin of the intrusions and their geodynamic implications.
