Heave-ho Slope
Hallett Peninsula () is a triangular, dome-shaped peninsula, long, with cliffs on its eastern seaboard side and on its west side. The peninsula extends from Cape Hallett to Cape Wheatstone and is joined to the mainland by a narrow ridge between Tucker Glacier and Edisto Inlet. It was so named by the New Zealand Geological Survey Antarctic Expedition, 1957–58, because Hallett Station on Seabee Hook was established at the north end of the peninsula. The peninsula is an elongated shield volcano complex similar to the Adare and Daniell peninsulas. It forms part of the Hallett Volcanic Province of the McMurdo Volcanic Group. Basalt Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial ...ic lava of the Hallett Peninsula has been dated to 6.4 ± 0.4 million years old.

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 part of the McMurdo Volcanic Group but 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 Tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Victoria Land
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide pa ...
