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.[1] Nepheline benmoreite magmas derived from mantle sources containing lherzolite xenoliths display similarities to some plutonic nepheline syenites.[2]
