The transport of carbon dioxide stored in the Earth’s lithospheric mantle beneath the Hyblean Plateau in southern Italy at a depth of approximately 50 to 150 kilometers is responsible for the exceptionally large CO2 emission of Mount Etna. That is the result of research conducted by an international team of geologists, including researchers from the Universities of Florence (Italy) and Cologne (Germany), and from the Istituto di Geologia Ambientale e Geoingegneria of the Italian National Research Council (CNR). To reach this conclusion, the team determined the ratios of a particular set of elements in the magmas emitted by the volcanoes using cutting-edge, high-precision measurement methods. The results have been published in the article “A carbon-rich lithospheric mantle as a source for the large CO2 emissions of Etna volcano (Italy)’ in the journal Geology.
