- •
The Bogda pillow basaltic lavas were erupted at ~ 311 Ma.
- •
Different characteristics of the pillow core and rim suggest post-magmatic seafloor hydrothermal alteration.
- •
The Bogda pillow lavas were sourced from a dry and depleted mantle source metasomatized by sediment-derived melts.
- •
The Bogda Late Carboniferous basalts were likely generated at a rear-arc or back-arc environment.
