- •
We assess the δ13C in a neutral mine drainage
- •
The DIC evolved sequentially by kinetic and equilibrium processes
- •
The δ13C of the carbonate was enriched by 0.7‰
- •
Carbon was released into the atmosphere and precipitated as carbonate
- •
20% of the carbon was outgassed and 12% was sequestered in sediments
