It remains challenging, however, to link the formation of mantle-sourced volatile-rich ultramafic magmas on continental shields to unique tectonic processes. Although extension of thick lithosphere may control deep-rooted volatile-rich and alkaline magmatism in some instances (Eggler, 1976; Bailey, ...
