- •
The pre- and syn-ore granites developed at Late Carboniferous to Early Permian.
- •
Molybdenite Re-Os dating show different mineralization ages at various deposits.
- •
The granites contain unfractionated and fractionated calc-alkaline I-type rocks.
- •
Sr-Nd-Pb-Hf-O isotopes indicate crustal assimilation was important.
- •
The granites are formed during subduction and syn-collision stages.
