Abstract:
To obtain the carbon and oxygen isotope compositions of seep carbonate, samples were ground into powder and send to the Fujian Normal University. About 1 mg powder was reacted with a few droplets of phosphoric acid under 70 °C for two hours. The CO₂ from the carbonate was purified and measured with a Gasbench attached to a Thermo MAT 253 mass spectrometer.
