- •
The Sanligang mafic dikes and granitoids formed at 871 Ma and 860 Ma, respectively.
- •
The mantle source of mafic dikes have been modified by slab-derived fluids.
- •
The Sanligang granitoids were generated by melting of the juvenile crust.
- •
The granitoids assimilate some residual mafic minerals in their source region.
- •
This igneous assemblage formed in an arc setting.
