Shackleton Mountains
The Shackleton Range is a mountain range in Antarctica. Rising at Holmes Summit to , it extends in an east–west direction for about between the Slessor and Recovery glaciers. The range was named after Sir Ernest Shackleton, leader of the British Imperial Trans-Antarctic Expedition (or "Shackleton's Expedition") of 1914–16. Surveys The Commonwealth Trans-Antarctic Expedition (CTAE), which in 1956 saw the range from the air, conducted a ground-level survey of its western part in 1957. The United States Navy photographed the range from the air in 1967. In 1968–69 and 1969–70, the British Antarctic Survey (based at Halley Station) conducted further ground surveys with support from US Navy C-130 Hercules aircraft.

Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metamorphic
Metamorphic rocks arise from the transformation of existing rock to new types of rock in a process called metamorphism. The original rock (protolith) is subjected to temperatures greater than and, often, elevated pressure of or more, causing profound physical or chemical changes. During this process, the rock remains mostly in the solid state, but gradually recrystallizes to a new texture or mineral composition. The protolith may be an igneous, sedimentary, or existing metamorphic rock. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface. They are classified by their protolith, their chemical and mineral makeup, and their texture. They may be formed simply by being deeply buried beneath the Earth's surface, where they are subject to high temperatures and the great pressure of the rock layers above. They can also form from tectonic processes such as continental collisions, which cause horizontal pressure, friction, and distorti ...

Clarkson Cliffs
Clarkson Cliffs () are ice-covered cliffs marked by rock exposures, rising to at the northeast edge of Fuchs Dome, Shackleton Range. They were photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey (BAS), 1968–71. They were named by the UK Antarctic Place-Names Committee after Peter D. Clarkson, BAS geologist, Halley Research Station, 1968–70, who worked in the area for four seasons, 1968–71, 1977–78; Head, BAS Mineralogy, Geology and Geochemistry Section, 1976–89; at Scott Polar Research Institute The Scott Polar Research Institute (SPRI) is a centre for research into the polar regions and glaciology worldwide.

Chevreul Cliffs
The Chevreul Cliffs () are a set of cliffs rising to about to the east of Mount Dewar in Pioneers Escarpment, Shackleton Range. They were photographed from the air by the U.S. Navy, 1967, and surveyed by the British Antarctic Survey, 1968–71.

Blanchard Hill
Blanchard Hill () is a hill between Mount Kelsey and Whymper Spur in the Pioneers Escarpment, eastern Shackleton Range. Photographed from the air by the U.S. Navy, 1967, it was surveyed by the British Antarctic Survey, 1968–71. It was named by the UK Antarctic Place-Names Committee after Robert Blanchard The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz'').

Blaiklock Glacier
Blaiklock Glacier () is a glacier long, flowing north from Turnpike Bluff, then northwest to Mount Provender and Mount Lowe in the western part of the Shackleton Range, Antarctica. It was first mapped in 1957 by the Commonwealth Trans-Antarctic Expedition (CTAE), and named for Kenneth V. Blaiklock, the leader of the advance party of the CTAE in 1955–56 and a surveyor with the transpolar party in 1956–58.
