- •
The Baogutu porphyry Cu deposit is a typical reduced porphyry Cu deposit.
- •
The granitoids from the Baogutu deposit are ilmenite-series I-type rocks.
- •
They are probably formed by mixing between mafic and felsic magma above slab window.
- •
The magmatic sources are mixed with less than 8% of subducted oceanic sediment.
