Figure 4

A plot of 13δC(CO2) versus 1/[CO2] (ppmV−1) data from the Teide summit cone and crater. This figure depicts three possible geochemical reservoirs: air, characterized by a and , deep-seated CO2 with and , and biogenic CO2 with and . Mixing trend between biogenic, air-derived, and deep-seated CO2 is represented by straight lines.
