Short summary

This study introduces an innovative method to analyze carbon isotopes in tiny amounts of CO2 produced during experiments that simulate conditions deep within the Earth. Using advanced tools, we measured both the composition and isotopic signature of CO2 in carbon-bearing fluids. This enables new studies of carbon exchange between rocks and fluids under extreme conditions, offering new insights into processes driving the deep carbon cycle and, ultimately, controlling the climate of our planet.
