Hornblende Bluffs
The Hornblende Bluffs () are prominent bluffs that rise to , located southeast of Mount Ellery and near the head of Suvorov Glacier, in the Wilson Hills of Antarctica. The feature was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, who found the rock here contains the mineral hornblende Hornblende is a complex inosilicate series of minerals.

Mount Ellery (Antarctica)
Wilson Hills () is a group of scattered hills, nunataks and ridges that extend NW-SE for about between Matusevich Glacier and Pryor Glacier in Antarctica. They were discovered by Lieutenant Harry Pennell, Royal Navy, on the Terra Nova Expedition in February 1911 during Robert Falcon Scott's last expedition, and named after Edward Adrian Wilson, a zoologist with the expedition, who perished with Scott on the return journey from the South Pole. Geological features Axthelm Ridge Axthelm Ridge () is a narrow ridge, 4 miles (6 km) long, 1.5 miles (2.4 km) southeast of Parkinson Peak. Mapped by United States Geological Survey (USGS) from surveys and U.S. Navy air photos, 1960–63. Named by Advisory Committee on Antarctic Names (US-ACAN) for Commander Charles E. Axthelm, U.S. Navy, Flag Secretary to the Commander of the U.S. Naval Support Force, Antarctica, during Operation Deep Freeze 1969 and 1970; executive officer on the USS ''Glacier'' during Operation Deep Freez ...

Suvorov Glacier
Suvorov Glacier () is a glacier, 5 nautical miles (9 km) wide, flowing east from the Wilson Hills and discharging into the sea south of Northrup Head and Belousov Point. Mapped by the Soviet Antarctic Expedition The Soviet Antarctic Expedition (SAE or SovAE) (russian: Советская антарктическая экспедиция, САЭ, ''Sovetskaya antarkticheskaya ekspeditsiya'') was part of the Arctic and Antarctic Research Institute of the So ..., 1958, and named after V.S.

Hornblende
Hornblende is a complex inosilicate series of minerals. It is not a recognized mineral in its own right, but the name is used as a general or field term, to refer to a dark amphibole. Hornblende minerals are common in igneous and metamorphic rocks. The general formula is . Physical properties Hornblende has a hardness of 5–6, a specific gravity of 3.0 to 3.6, and is typically an opaque green, dark green, brown, or black color. It tends to form slender prismatic to bladed crystals, diamond-shaped in cross-section, or is present as irregular grains or fibrous masses. Its planes of cleavage intersect at 56° and 124° angles. Hornblende is most often confused with the pyroxene series and biotite mica, which are also dark minerals found in granite and charnockite. Pyroxenes differ in their cleavage planes, which intersect at 87° and 93°. Hornblende is an inosilicate (chain silicate) mineral, built around double chains of silica tetrahedra. These chains extend the length of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
