Everard Ranges
The Everard Ranges, officially known as The Everard Ranges, is a range of low rounded granite hills located in the Australian state of South Australia in the Aṉangu Pitjantjatjara Yankunytjatjara lands about west of Mintabie. It is of Palaeocene origin between 20 and 60 million years ago, in Central Australia . Rising into domes above a Cenozoic peneplain, which is here about above sea level., they were named by Ernest Giles. after a cattle station called " Everard Park", and consist of monoliths or bornhardts, rich in caves and overhangs with Aboriginal rock painting galleries. The ranges are similar to Uluru and Kata Tjuta. Giles described them in his book, ''Australia Twice Traversed'' as follows: ''"Arriving at the first hills of the Everard, I found they were all very peculiar, bare, red, granite mounds, being the most extraordinary ranges one could possibly imagine, if indeed any one could imagine such a scene. They have thousands of acres of bare rock, pil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Kata Tjuta
Kata Tjuṯa / The Olgas (Pitjantjatjara: , lit. 'many heads'; ) is a group of large, domed rock formations or bornhardts located about southwest of Alice Springs, in the southern part of the Northern Territory, central Australia. Uluṟu / Ayers Rock, located to the east, and Kata Tjuṯa / The Olgas form the two major landmarks within the Uluṟu-Kata Tjuṯa National Park. The park is considered sacred to the Aboriginal people of Australia. The 36 domes that make up Kata Tjuṯa / Mount Olga cover an area of are composed of conglomerate, a sedimentary rock consisting of cobbles and boulders of varying rock types including granite and basalt, cemented by a matrix of coarse sandstone. The highest dome, Mount Olga, is above sea level, or approximately above the surrounding plain higher than Uluṟu). [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of South Australia
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations have different plants and animals. Because ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Camaenidae
Camaenidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea, the typical snails and their allies. This is one of the most diverse families in the clade Stylommatophora. These snails occur in a wide variety of habitats in the tropics of Eastern Asia and Australasia. A large American group, which is mainly represented by species from the Caribbean, has, until recently, also been subsumed under the Camaenidae. However, latest molecular phylogenetic studies showed that these species represent a different family, the Pleurodontidae. This molecular study also implies that the Bradybaeninae, previously being treated as a distinct family within the Helicoidea, is a junior synonym of the Camaenidae. Anatomy Camaenid shells are often quite large (25–50 mm), but a number of species also have small shells (<5 mm). Shells reveal a remarkable diversity in shape and colour, which is partly linked with their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Radiation
An evolutionary radiation is an increase in taxonomic diversity that is caused by elevated rates of speciation, that may or may not be associated with an increase in morphological disparity. Radiations may affect one clade or many, and be rapid or gradual; where they are rapid, and driven by a single lineage's adaptation to their environment, they are termed adaptive radiations. Examples Perhaps the most familiar example of an evolutionary radiation is that of placental mammals immediately after the extinction of the non-avian dinosaurs at the end of the Cretaceous, about 66 million years ago. At that time, the placental mammals were mostly small, insect-eating animals similar in size and shape to modern shrews. By the Eocene (58–37 million years ago), they had evolved into such diverse forms as bats, whales, and horses. Other familiar radiations include the Avalon Explosion, the Cambrian Explosion, the Great Ordovician Biodiversification Event, the Carboniferous-Earliest Perm ...

Mimili
Mimili is an Aboriginal community in the Anangu Pitjantjatjara Yankunytjatjara Lands in South Australia, comprising one of the six main communities on "The Lands" (the others being Amata, Pukatja, Kaltjiti, Indulkana and Pipalyatjara). At the 2016 Australian census, Mimili had a population of 243. After European settlement in the 19th century, there was a cattle station on the land, which was named Everard Park. The station was purchased by the South Australian government in 1972 before transferring it to the traditional owners. Geography Mimili is situated in South Australia, within the APY, about west of the Stuart Highway and south of Alice Springs. History and significance According to the local Pitjantjatjara people, Mimili is the original name. The community grew around the Everard Park cattle station, and is surrounded by the rocky Everard Ranges. The land was handed back to the traditional owners in 1972. The settlement was funded by the federal government a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
