Mantle-derived CO2-rich magma ascends rapidly through the lithospheric column, supporting upward transport of large mantle-xenoliths and xenocryst (>30vol%) loads to the (sub-)surface within days. The regional magmatism during which such pulses occur is typically well characterized in terms of ge...
