6. Conclusions
- (1)
- New LA–ICP–MS zircon U–Pb geochronology indicates that the granodiorite porphyry, gabbro, and granite porphyry were emplaced at 321.8 ± 3.1 Ma, 313.5 ± 1.2 Ma and 309.8 ± 2.5 Ma, respectively.
- (2)
- The zircon trace elements of the Carboniferous intrusions in the Tuwu-Yandong belt imply that the granodiorite porphyry is likely derived from a more oxidized and hydrous magma source than that of the gabbro and granite porphyry, which may favor the formation of porphyry Cu deposits.
- (3)
- The adakitic granodiorite porphyry is derived from the partial melting of the subducted oceanic slab, with subsequent interactions with mantle peridotite. The high-Al gabbro is derived from the partial melting of a depleted mantle wedge hydrated by slab-released fluids, while the non-fractionated I-type granite porphyry is derived from the partial melting of the juvenile lower crust.
- (4)
- The northward flat subduction of the Kangguer ocean slab at ca. 335–315 Ma facilitated the formation of the adakites and associated porphyry Cu mineralization in the Tuwu-Yandong belt. After the prolonged flat subduction, slab rollback may have occurred at ca. 314–310 Ma.
