Basalt - Basalt Basalt is an extrusive igneous rock, sometimes porphyritic, and is often both fine-grained and dense. Basalt in the tops of subaerial lava flows and cinders will often be highly vesiculated, imparting a lightweight "frothy" texture to the rock. The term basalt is often casually applied to shallow intrusive rocks with a composition typical of basalt, but rocks of this composition with a phaneritic groundmass should generally be referred to as gabbro. The crustal portions of oceanic tectonic plates are predominantly made of basalt. Unweathered basalt is frequently black to greenish-black in color, characterized by a preponderance of calcic plagioclase feldspars and pyroxene together with minor amounts of accessory minerals such as olivine. Basaltic cinders are often red. Glass may be present, particularly as rinds on.

Operation Basalt - Operation Basalt During World War II, Operation Basalt was a small raid on the German occupied British Channel Island of Sark, on the night of 3/4 October, 1942. It was conducted by ten men of the SOE's Small Scale Raiding Force, and No.12 Commando with the object of an offensive reconnaissance and capturing prisoners. Nine of the raiders broke into the house of a local while the tenth went to a covert rendezvous with an SOE agent. The occupant of the house, Frances Pittard, proved very informative and advised there were about 20 Germans in the nearby Dixcart Hotel. She also declined an offer to take her back to England. In front of the hotel was a long hut type building, apparently unguarded. This annex comprised a.
Venus (planet) - at some time in the distant past. In addition to this unusual retrograde rotation, the periods of Venus's rotation and of its orbit are synchronized in such a way that it always presents the same face toward Earth when the two planets are at their closest approach (5.001 Venusian days between each inferior conjunction). This may be the result of tidal locking, with tidal forces affecting Venus's rotation whenever the planets get close enough together, or it may simply be a coincidence. Venus has two major continent-like highlands on its surface, rising over vast plains. The northern highland is named Ishtar Terra and has Venus's highest mountains, named the Maxwell Montes after James Clerk Maxwell, which surround the plateau Lakshmi Planum. Ishtar Terra is about the size of Australia. In the.

Kirkcudbrightshire - is Glen Trool, not far from the district of Carrick in Ayrshire, the fame of which rests partly on the romantic character of its scenery, which is very wild around Loch Trool, and more especially on its associations with Robert the Bruce. It was here that when most closely beset by his enemies, who had tracked him to his fastness by sleuth hounds, Bruce with the aid of a few faithful followers won a surprise victory over the English in 1307 which proved the turning-point of his fortunes. Geology Silurian and Ordovician rocks are the most important in this county; they are thrown into oft-repeated folds with their axes lying in a N.E.-S.W. direction. The Ordovician rocks are graptolitic black shales and grits of Llandeilo and Caradoc age. They occupy all.
Kilbourne hole - a large crater; thus, it is not necessary for the lava and magma to build up a mountainous deposit. The crater is thought to be 80,000 years old. The volcanic features around El Paso and vicinity are part of the Rio Grande Rift, which extends northward into Wyoming. Description of the crater Basalt cliffs of Kilbourne hole, looking north from south lip of crater The hole is over a mile wide, and over 300 feet deep. Two basalt cliffs inside the crater, with the characteristic reddish purple hexagonal columns occupy the northeast and southeast sides of the crater. The cliffs are about 40 feet high. Layers of ashfall and crumbling sediment also rise about 40 feet high, on the south rim of the crater. This ashfall section will not support your.
Josiah Wedgwood - pottery she purchased "Queen's Ware", and trumpeted the royal association in his paperwork and stationery. As a burgeoning industrialist, Wedgwood was a major backer of the Trent and Mersey Canal dug between the River Trent and River Mersey, during which time he became friends with Erasmus Darwin. Later that decade, his burgeoning business caused him to move from the smaller Ivy Works to the newly- built Etruria Works, which would run for 180 years. The factory was so-named after the Etruria district of Italy, where black porcelain dating to Etruscan times was being excavated. Wedgwood found this porcelain inspiring, and his first major commercial success was its duplication with what he called "Black Basalt". Not long after the new works opened, continuing trouble with his smallpox-afflicted knee made necessary the amputation.
John Flaxman - was defeated, the prize being adjudged by the president, Sir Joshua Reynolds, to another competitor named Engleheart. tThis reverse proved no discouragement, and indeed seemed to have helped cure Flaxman of a tendency to conceit which made Thomas Wedgwood say of him in 1775: "It is but a few years since he was a most supreme coxcomb." He continued to work diligently, both as a student in the schools and as an exhibitor in the galleries of the Academy, occasionally also attempting diversions into the sister art of painting. To the Academy he contributed a wax model of Neptune (1770); four portrait models in wax (1771); a terracotta bust, a wax figure of a child, a figure of History (1772); a figure of Comedy, and a relief of a Vestal (1773)..
Igneous rock - Porphyritic textures are an intermediate situation between the previous two: the groundmass of the rock has an aphanitic texture, but crystals (termed in this particular occurrence as phenocrystals) are visible to unaided eye. If a molten magma cools at extremely high rates, allowing no crystallization, the result is a vulcanic glass called obsidian. Crystal shapes are also an important feature in defining correct igneous textures. They can be: Euedral, if the crystallographic shape is preserved Subeuedral, if only part is preserved Anedral, if the crystal presents no recognizable crystallographic direction =Chemical composition= Igneous rocks can be subdivided according to two main chemical parameters: contents of silica: acid igneous rocks present a high silica content (ex: granite) basic igneous rocks have low silica content (ex: basalt) intermediate igneous rocks contents of quartz,.
Island arc - under another and is melted into magma by the intense heat. Oceanic plates are composed of basalt, a lighter material than the material that composes the upper mantle. When melted this material becomes very boyant and rises up to the surface where it becomes lava and forms volcanos in the shape of an arc. Due to the reactions of the metamorphic and igneous rocks, it is not uncommon to find black-green beaches composed of olivine eroded from volcanic cones. On the ocean side of the island arc is a deep trench where the subducted plate sinks below the subducting plate. This trench is created by the friction of the subducting plate pulling the leading edge of the overbearing plate downward. Great frictinal forces heat the rock on both plates in this.
Hadad - Benhadad, or son of Hadad. just as a series of Egyptian monarchs are known to have been accustomed to call themselves sons of Amon-Ra. The name-element 'Hadad' is found in the names of kings, such as Benhadad, the king of Syria whom Asa, king of Judah, employed to invade the northern kingdom, Israel, according to 1 Kings 15:18), or Hadadezer, the Syrian king defeated by David. In the 9th or 8th century BCE, the name of Bar-Hadad, king of Aram, is inscribed on his votive basalt stele dedicated to Melqart, found in Bredsh, a village north of Aleppo (National Museum, Aleppo, accession number KAI 201). The word Hadadrimmon, for which the inferior reading Hadarrimmon is found in some manuscripts in the phrase "the mourning of (or at) Hadadrimmon" (Zech xii. ii),.
Hells Canyon - the North American West. Until a million years ago, the Owyhee Mountains acted as a dam between the Snake River and its current confluence with the Columbia River, creating a vast lake in what is now southwestern Idaho. When the mountains were finally breached, the Snake roared northward, cutting a giant chasm through the volcanic rock. Most of the older rocks we see in the canyon came from underwater volcanoes when Hells Canyon's terrains were part of an island arc in the mid-Pacific Ocean. These complex terrains glued themselves to North America about 150 million years ago as a result of tectonic plate movement. Vast areas were later covered with successive lava flows as recently as 6 million years ago. Uplifting from deep in the earth's core formed the Seven Devils.
He-Man - usually pull through. There is also Ram Man, whose head is useful for knocking things down, and Stratos, who flies. He-Man also has a sister, named She-Ra, who only occasionally appears in the series but was given a series of her own. She-Ra was introduced in the feature length animated film He-Man and She-Ra: The Secret of the Sword. She-Ra's own show ran from 1985 to 1986. He-Man's chief adversary is Skeletor. Though his origin is mysterious, some believe Skeletor to be Keldor... King Randor's younger brother. Skeletor is a blue muscleman with a skull for a head, wearing a cowl. Skilled in dark magic as well as all forms of combat; Skeletor's weapon of choice is his Havok Staff: a ram's skull atop a large rod which serves to channel.
History of sculpture - The Venus of Willendorf (30,000 - 25,000 BC), from the area of Willendorf, Austria, is a well known example. Later, in the Near East, (the area between the Tigris River and the Euphrates River), the Sumerian, Akkadian and Babylonian kingdoms flourished. Materials used for sculpture during this time included basalt, diorite (a type of dark, coarse-grained stone), sandstone and alabaster. Copper, gold, silver, shells and a variety of precious stones were used for high quality sculpture and inlays. Clay was used for pottery and terra cotta sculpture. Stone was generally rare and had to be imported from other locations. Sculptures from the Sumerian and Akkadian period generally had large, staring eyes, and long beards on the men. Votive stone sculptures of this type from 2700 BC were discovered at Tell Asmar..
Hornblende - A variety of hornblende that contains less than 5% of iron oxides is gray to white in color and named edenite, from its locality in Edenville, New York. Very dark brown to black hornblendes which contain titanium ordinarily are called basaltic hornblende from the fact that they are usually a constituent of basalt and related rocks. The word hornblende is derived from the German horn and blende, to blind or dazzle. The term blende was often used to refer to a brilliant non-metallic lustre, for example, zincblende, and pitchblende, a lustrous form of uraninite. See also: List of minerals.
Hydrothermal circulation - both cases the principle is the same: cold dense seawater sinks into the seafloor and is heated at depth whereupon it rises back to the seafloor due to its lesser density. The heat source for the active vents is the newly formed basalt, and, for the highest temperature vents, the underlying magma chamber. The heat source for the passive vents is the still-cooling older basalts. Heat flow studies of the seafloor suggest that basalts within the oceanic crust take millions of years to completely cool as they continue to support passive hydrothermal circulation systems. Hydrothermal vents are locations on the seafloor where hydrothermal fluids mix into the overlying ocean. Perhaps the best known vent forms are chimneys. See also: Convection This article is a stub.

Gabbro - coarse-grained intrusive igneous rock chemically equivalent to basalt. It is a plutonic rock, formed when molten magma is trapped beneath the Earth's surface and cools slowly into a hard, coarsely crystalline mass. It is dense, greenish or dark-colored and contains varied percentages of plagioclase feldspar, pyroxene, amphibole, and olivine (called olivine gabbro when olivine is present in large quantities). Quartz gabbros are also known to occur and are probably derived from magma that was oversaturated with silica. On the other hand, essexites represent gabbros whose parent magma had an insufficiency of silica resulting in the formation of nephelite. Gabbro is too fragile to use in construction, but often contains valuable amounts of chromium, nickel, cobalt, gold, silver, platinum, and copper sulfides. See also: List of minerals.
