McMurdo Volcanic Group

The McMurdo Volcanic Group is a large group of Cenozoic volcanic rocks in the western Ross Sea and central Transantarctic Mountains areas of Antarctica. It is one of the largest provinces of alkaline volcanism in the world, having formed as a result of continental rifting along the West Antarctic Rift System. The McMurdo Volcanic Group is part of the Western Ross Supergroup, a stratigraphic unit that also includes the Meander Intrusive Group.

Subdivisions
Three subprovinces comprise the McMurdo Volcanic Group, namely the Hallett, Melbourne and Erebus volcanic provinces. The Balleny Volcanic Province along the Balleny Fracture Zone in the Southern Ocean was originally defined as a part of the McMurdo Volcanic Group but it is now excluded due to its location on oceanic crust with no obvious geographic or tectonic relationship to the other McMurdo volcanic provinces.

Hallett Volcanic Province
The Hallett Volcanic Province in northern Victoria Land is situated along the margin of the Transantarctic Mountains. It consists of a 260 km long chain of four major elongated shield volcano complexes that were originally interpreted to have erupted subglacially under a larger Antarctic ice sheet. Later studies showed that they erupted in a subaerial environment instead.
