Benmoreite
Benmoreite is a silica-undersaturated volcanic rock of intermediate composition. It is a variant of trachyandesite and belongs to the alkalic suite of igneous rocks. An origin by fractionation from basanite through nepheline hawaiite to nepheline benmoreite has been demonstrated for a volcanic suite in the McMurdo Volcanic Group of late Cenozoic age in McMurdo Sound area. Nepheline benmoreite magmas derived from mantle sources containing lherzolite xenoliths display similarities to some plutonic nepheline syenites.
