Abstract Alkaline-peralkaline igneous systems are promising sources of Rare Earth Elements (REE). Preservation bias has resulted in a gap the geological record for alkaline-peralkaline magmatic systems, with hypabyssal plumbing system linking magma chambers to extrusive volcanic rocks poorly represented. Large plutonic varieties these often proposed have fed (now eroded) volcanoes, and current ...
