- •
Seven pyrite separates from the Zijinshan Cu-Au deposit yield an Re-Os isochron age of 103 ± 4 Ma, coeval with the Luoboling Cu-Mo deposit.
- •
The initial Os isotope composition of 0.45 suggests that the Os in the hydrothermal fluids may be derived from the crust with input from the mantle.
- •
Analysis of one pyrite from the deposit shows a disturbance of the Re–Os system, and thus it should be cautious in the interpretation of such data.
