Evidence of Tectonic Control on the Geochemical Features of the Volatiles Vented along the Nebrodi-Peloritani Mts (Southern Apennine Chain, Italy)

Figure 2

CH4-O2-CO2 composition of the gases dissolved in the studied waters. The dashed arrows show the trends produced by the addition and dissolution of CO2 and addition of CH4 to an atmospheric gas assemblage (see text for details). ASW: air saturated water. Open black marks: samples from Nebrodi Mts; blue filled marks: samples from Peloritani Mts. Labels refer to sample numbers as in Tables 1ā€“4.
