Constraints on timing and origin of the Dayinjian intrusion and associated molybdenum mineralization, western Dabie orogen, central China
The Early Cretaceous geology of the western Dabie Mountains is characterized by widespread granitoid pluton emplacement and associated Mo mineralization. We report LA-ICP-MS zircon U-Pb and molybdenite Re-Os dating, whole-rock chemical and Sr-Nd-Pb isotopic compositions, as well as in situ zircon Hf isotopic geochemistry, for the Dayinjian granite in the region to better constrain its petrogenesis. U-Pb zircon dating yielded a weighted average age of 124.9 ± 1.3 Ma (mean square weighted...[Show more]
