- •
Taiyangshan deposit formed in a transition regime from syn-collision to post-collision.
- •
Magma was derived from partial melting of ancient Meso- to Neoproterozoic lower continental crust.
- •
This crust was likely metasomatized during earlier subduction.
- •
Magmas may have been contaminated with lithospheric mantle derived magma triggered by MASH.
- •
The resultant hybrid magmas contribute to its fluid and metal sources.
