- •
Porphyry Cu(Au/Mo) deposits are diagnostic to compressional thickened continental crust.
- •
VMS deposits are diagnostic to extensional thin arc-related basins.
- •
Orogenic gold deposits are diagnostic to transpressional boundary.
- •
Coeval porphyry-type and VMS-type ore deposits occurred widely throughout the Altaids.
- •
Porphyry deposits outline the distribution of diverse-origin continental fragments, which is much smaller than the whole area of the Altaids.
- •
The ages of the orogenic gold deposits indicate that the orogenic duration is outside the time bracket of the Altaids.
