The high flux of subaerial volcanic CO2 emissions around the circum-Mediterranean region requires the involvement of an unusually carbon-rich reservoir, but the origin of which is still unclear. Here, we aim to resolve this problem by analyzing Mg and Zn isotopes for the widely distributed mafic potassic to ultrapotassic lavas in this region. These K-rich lavas have lower δ 26Mg but similar δ 66Zn compared to mid-ocean ridge basalts (MORB). No known magmatic processes can explain the isotopic data, ...
