The Hanson Formation (also known as the Shafer Peak Formation) is a geologic formation on Mount Kirkpatrick and north Victoria Land, Ross Dependency, Antarctica.It is one of the two major dinosaur-bearing rock groups found on Antarctica to date; the other is the Snow Hill Island Formation and related formations from the Late Cretaceous of the Antarctic Peninsula.
West Antarctica was partially in the northern hemisphere, and during this period large amounts of sandstones, limestones and shales were deposited. East Antarctica was at the equator, where sea-floor invertebrates and trilobites flourished in the tropical seas. By the start of the Devonian period (416 Ma) Gondwana was in more southern latitudes ...
Fossil proxies of near-shore sea surface temperatures and seasonality from the late Neogene Antarctic shelf. Naturwissenschaften 100:699-722; J. W. Collinson, D.C. Pennington, and N.R. Kemp. 1986. Stratigraphy and petrology of Permian and Triassic fluvial deposits in northern Victoria Land, Antarctica. Antarctic Research Series 46:211-242
The Antarctic Peninsula, roughly 1,000 kilometres (650 mi) south of South America, is the northernmost portion of the continent of Antarctica. Like the associated Andes, the Antarctic Peninsula is an excellent example of ocean-continent collision resulting in subduction. [1]
Scientists working in the Antarctic region have discovered a type of seaweed living at depths some 100 metres below the surface. Researchers hailed the discovery of red alga Palmaria decipiens ...
The Beacon Supergroup is a geological formation exposed in Antarctica and deposited from the Devonian to the Triassic). The unit was originally described as either a formation or sandstone, and upgraded to group and supergroup as time passed. It contains a sandy member known as the Beacon Heights Orthoquartzite. [1]
Blood Falls, 2006 Blood Falls, at the toe of Taylor Glacier, 2013. Blood Falls is an outflow of an iron(III) oxide–tainted plume of saltwater, flowing from the tongue of Taylor Glacier onto the ice-covered surface of West Lake Bonney in the Taylor Valley of the McMurdo Dry Valleys in Victoria Land, East Antarctica.
Superficial deposits (or surficial deposits [1]) refer to geological deposits typically of Quaternary age (less than 2.6 million years old) for the Earth. These geologically recent unconsolidated sediments may include stream channel and floodplain deposits, beach sands, talus gravels and glacial drift and moraine .
