The Breadknife
The Breadknife is a volcanic dyke in New South Wales, Australia. It is nearly 90 metres high, but often is only 4 m wide, which is particularly rare. The Breadknife was part of a large shield volcano, that first erupted about 17 million years ago and stopped about 13 million years ago. It is composed of peralkaline trachyte. Nearby volcanic remnants include the Belougery Spire, Belougery Split Rock, Crater Bluff, Bluff Mountain and Mount Exmouth. A network of walking tracks are used to access the steep mountains and ridges surrounding the dyke. The shortest walk completely around the Breadknife is hard and steep, taking roughly five hours to complete. Origin Story A huge shield-shaped volcano formed as volcanic explosions occurred over millions of years. This shield volcano rose about 1,000 m and is now largely eroded, forming the Warrumbungles. The Breadknife was formed when hot magma spread through a soft rock. When the magma solidified and bec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Extinct Volcanism
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanism Of Australia
The geology of Australia includes virtually all known rock types, spanning a geological time period of over 3.8 billion years, including some of the oldest rocks on earth. Australia is a continent situated on the Indo-Australian Plate. Components Australia's geology can be divided into several main sections: the Archaean cratonic shields, Proterozoic fold belts and sedimentary basins, Phanerozoic sedimentary basins, and Phanerozoic metamorphic and igneous rocks. Australia as a separate continent began to form after the breakup of Gondwana in the Permian, with the separation of the continental landmass from the African continent and Indian subcontinent. Australia rifted from Antarctica in the Cretaceous. The current Australian continental mass is composed of a thick subcontinental lithosphere, over thick in the western two-thirds and thick in the younger eastern third. The Australian continental crust, excluding the thinned margins, has an average thickness of , with a ran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Warrumbungle National Park
Warrumbungle National Park is a heritage listed national park located in the Orana region of New South Wales, Australia. The national park is located approximately northwest of Sydney and contained within . The park attracts approximately visitors per annum. The national park is based on the geographical Warrumbungle Mountain Range, sometimes shortened to the Warrumbungles, and thus the park name is often heard in the plural. The park lies within the Pilliga Important Bird Area, so identified by BirdLife International because of its importance for a range of woodland bird species, many of which are threatened. Warrumbungle National Park was added to the Australian National Heritage List in December 2006. On 4 July 2016, the park was the first within Australia to be certified as a Dark Sky Park by the International Dark Sky Association.

List Of Volcanoes In Australia
This is a list of active, dormant and extinct volcanoes in Australia and its island territories. Note that the term volcano is used loosely as it can include groups of related volcanoes and vents that erupted at similar times with lava of related origin. The lists provided below are mainly volcanoes of Cenozoic aged, with some notable older (Mesozoic and Paleozoic aged), volcanoes included. There are no volcanoes on the Australian mainland that have erupted since European settlement, but some volcanoes in Victoria, South Australia and North Queensland could have been witnessed by Aboriginal people several thousand years ago. There are active volcanoes in the Heard and McDonald Islands. Australian states Queensland New South Wales Victoria South Australia South Australia's volcanoes are the youngest in Australia, and erupted within the memory of local Indigenous peoples. They are all in the Limestone Coast region, in the Mount Burr Range. They are considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anime
is Traditional animation, hand-drawn and computer animation, computer-generated animation originating from Japan. Outside of Japan and in English, ''anime'' refers specifically to animation produced in Japan. However, in Japan and in Japanese, (a term derived from a shortening of the English word ''animation'') describes all animated works, regardless of style or origin. Animation produced outside of Japan with similar style to Japanese animation is commonly referred to as anime-influenced animation. The earliest commercial Japanese animations date to 1917. A characteristic art style emerged in the 1960s with the works of cartoonist Osamu Tezuka and spread in following decades, developing a large domestic audience. Anime is distributed theatrically, through television broadcasts, Original video animation, directly to home media, and Original net animation, over the Internet. In addition to original works, anime are often adaptations of Japanese comics (manga), light novels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Let's Dance (David Bowie Song)
"Let's Dance" is a song by English singer-songwriter David Bowie, originally included as the title track of his 1983 album of the same name. Co-produced by Nile Rodgers of Chic, it was recorded in late 1982 at the Power Station in New York City. With the assistance of engineer Bob Clearmountain, Rodgers transformed the song from its folk origins to a dance number through studio effects and new musicians Bowie had yet to work with. Bowie hired then-unknown Texas guitarist Stevie Ray Vaughan, who added a blues-edge. Embracing rock, funk, dance, new wave and post-disco, the full-length seven-minute track features numerous solos, including trumpet, saxophone, guitar and percussion. Several music elements, from the bassline and the breakdown, were based on Rodgers' work with Chic, while the rising vocal intros were taken from the Beatles' version of "Twist and Shout". The lyrics describe a couple dancing under the moonlight and possess a sense of peril and ominousness. Released a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dike (geology)
A dike or dyke, in Geology, geological usage, is a sheet of rock that is formed in a Fracture (geology), fracture of a pre-existing rock body. Dikes can be either Intrusive rock, magmatic or Sedimentary rock, sedimentary in origin. Magmatic dikes form when magma flows into a crack then solidifies as a sheet intrusion, either cutting across layers of rock or through a contiguous mass of rock. Clastic dikes are formed when sediment fills a pre-existing crack.Essentials of Geology, 3rd Ed, Stephen Marshak Magmatic dikes A magmatic dike is a sheet of igneous rock that cuts across older rock beds. It is formed when magma fills a fracture in the older beds and then cools and solidifies. The dike rock is usually more resistant to weathering than the surrounding rock, so that erosion exposes the dike as a natural wall or ridge. It is from these natural walls that dikes get their name. Dikes preserve a record of the fissures through which most mafic magma (fluid magma low in silica) reac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Bowie
David Robert Jones (8 January 194710 January 2016), known professionally as David Bowie ( ), was an English singer-songwriter and actor. A leading figure in the music industry, he is regarded as one of the most influential musicians of the 20th century. Bowie was acclaimed by critics and musicians, particularly for his innovative work during the 1970s. His career was marked by reinvention and visual presentation, and his music and stagecraft had a significant impact on popular music. Bowie developed an interest in music from an early age. He studied art, music and design before embarking on a professional career as a musician in 1963. "Space Oddity", released in 1969, was his first top-five entry on the UK Singles Chart. After a period of experimentation, he re-emerged in 1972 during the glam rock era with his flamboyant and androgynous alter ego Ziggy Stardust (character), Ziggy Stardust. The character was spearheaded by the success of Bowie's single "Starman (song), Starma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magma
Magma () is the molten or semi-molten natural material from which all igneous rocks are formed. Magma is found beneath the surface of the Earth, and evidence of magmatism has also been discovered on other terrestrial planets and some natural satellites. Besides molten rock, magma may also contain suspended crystals and gas bubbles. Magma is produced by melting of the mantle or the crust in various tectonic settings, which on Earth include subduction zones, continental rift zones, mid-ocean ridges and hotspots. Mantle and crustal melts migrate upwards through the crust where they are thought to be stored in magma chambers or trans-crustal crystal-rich mush zones. During magma's storage in the crust, its composition may be modified by fractional crystallization, contamination with crustal melts, magma mixing, and degassing. Following its ascent through the crust, magma may feed a volcano and be extruded as lava, or it may solidify underground to form an intrusion, such as a ...
