Characterization of the HIMU Mantle Source from Noble Gas Isotopes in Volcanic Gas Emissions in São Tomé (Cameroon Volcanic Line)
{{output}}
The source of volcanism in the Cameroon volcanic line remains unresolved. To better constrain the mantle components involved, we measure light noble gas (He-Ne-Ar) isotopes and, for the first time, heavy noble gas (Kr-Xe) isotopes in mantle-derived gases from ... ...
