- •
The Caosiyao giant porphyry Mo deposit formed during 147–150 Ma.
- •
Host granitoids are silica and alkali rich, highly oxidized and differentiated.
- •
Host granitoids show crustal component as envisaged by high negative εHf(t) values.
- •
Mo mineralization was associated with an extensional tectonic setting.
- •
It was caused by far-field tectonics related to the Paleo-Pacific subduction.
