Geochronology, geochemistry and Sr–Nd–Hf isotopic compositions of Late Cretaceous–Eocene granites in southern Myanmar: Petrogenetic, tectonic and metallogenic implications

The geochronology, petrogenesis and tectonic setting of granites associated with tin–tungsten mineralization in southern Myanmar remain unclear. This work presents whole-rock geochemical, Sr–Nd isotopic, and zircon U–Pb and Hf isotopic data for felsic intrusions in the Sibusima terrane. Zircon U–Pb dating indicates formation in the Late Cretaceous–Early Eocene (~84–48 Ma) and suggests that these intrusions likely represent a southward extension...
