Magmatic volatiles can be considered as the surface fingerprint of active volcanic systems, both during periods of quiescent and eruptive volcanic activity. The spatial variability of gas emissions at Earth’s surface is a proxy for structural discontinuities in the subsurface of volcanic systems. We conducted extensive and regular spaced soil gas surveys within the Los Humeros geothermal field to improve the understanding of the structural control on fluid flow.

- Data Quality
- Carbon isotopic analyses were performed with a GC-C-IRMS system consisted of a GC (6890N, Agilent Technology, USA) connected to a GC-C/TC III combustion device coupled via open split to a MAT 253 mass spectrometer (ThermoFisher Scientific, Germany) under continuous flow. The quality of the carbon isotope measurements was checked by direct injection a CO2-reference gas with known δ13C into the mass spectrometer during each run as well as by daily measurements of n-alkane gas standard (n-C1 to n-C6). The standard deviation is < 0.5 ‰. Herein, all results are reported in the standard notation δ as per mille (‰) deviations relative to the PDB (Pee Dee Belemnite) standard.
- Supplemental Information
94 soil gas samples were collected for δ13CCO2 isotopic analyses (Table 1 & 2) from areas of low, intermediate and high CO2 efflux to constrain the origin of...
