- •
The isotopic geochemistry of Svecofennian carbonatites and lamprophyres is presented.
- •
A two-stage model for mantle metasomatism in the Svecofennian Domain is supported.
- •
The Svecofennian subcontinental lithospheric mantle bears EMII characteristics.
- •
Recycling of organic carbon resulted in highly negative 未13C in mantle carbonates.
