Alexander McKay (geologist)
Alexander McKay (11 April 1841 – 8 July 1917) was a New Zealand geologist. He was born in Carsphairn, Kirkcudbrightshire, Scotland on 11 April 1841. McKay reached New Zealand in 1863 where he spent a number of years prospected for gold. A meeting with Julius von Haast saw a change of direction in which McKay, largely self-taught, undertook geological mapping and fossil collecting expeditions throughout the islands. In 1872 James Hector appointed him to the Geological Survey of New Zealand.Cherry Lewis, Simon J. Knell (2009) "The Making of the Geological Society of London"pp350 Geological Society of London. Retrieved February 2015 During his geological work McKay took numerous photographs. He invented a telephoto lens and also techniques for taking images of geological collections and fossils. McKay's greatest achievement was to free New Zealand sciences from the strictures of European-based thinking, developing new theories, of worldwide importance, on block faulting in ...

Geologist
A geologist is a scientist who studies the solid, liquid, and gaseous matter that constitutes Earth and other terrestrial planets, as well as the processes that shape them. Geologists usually study geology, earth science, or geophysics, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field research (field work) is an important component of geology, although many subdisciplines incorporate laboratory and digitalized work. Geologists can be classified in a larger group of scientists, called geoscientists. Geologists work in the energy and mining sectors searching for natural resources such as petroleum, natural gas, precious and base metals. They are also in the forefront of preventing and mitigating damage from natural hazards and disasters such as earthquakes, volcanoes, tsunamis and landslides. Their studies are used to warn the general public of the occurrence of these events. Geologists are also important contributors to climate ch ...

Carsphairn
Carsphairn ( gd, An Còrsa Feàrna) is a village in the historic county of Kirkcudbrightshire in Dumfries and Galloway, Scotland. It is located about halfway between Dalmellington and St John's Town of Dalry, on the A713 road. Carsphairn annual sheep show is held in the village. Cairnsmore of Carsphairn is to the north east of the village in the Carsphairn and Scaur Hills. To the west is the ridge of the Rhinns of Kells in the Galloway Hills. The village has many features ranging from an ancient stone circle to a nuclear listening post (now disused), and includes local amenities such as a shop, tearoom, a primary school and a village hall. Carsphairn Church, Church of Scotland was built in 1815 on site of an earlier church. Additions and alterations in the 1930s include the apse and porch.

Kirkcudbrightshire
Kirkcudbrightshire ( ), or the County of Kirkcudbright or the Stewartry of Kirkcudbright is one of the historic counties of Scotland, covering an area in the south-west of the country. Until 1975, Kirkcudbrightshire was an administrative county used for local government. Since 1975, the area has formed part of Dumfries and Galloway for local government purposes. Kirkcudbrightshire continues to be used as a registration county for land registration. A lower-tier district called Stewartry covered the majority of the historic county from 1975 to 1996. The area of Stewartry district is still used as a lieutenancy area. Dumfries and Galloway Council also has a Stewartry area committee. Kirkcudbrightshire forms the eastern part of the medieval lordship of Galloway, which retained a degree of autonomy until it was fully absorbed by Scotland in the 13th century. In 1369, the part of Galloway east of the River Cree was placed under the control of a steward based in Kirkcudbright and so t ...

Scotland
Scotland (, ) is a country that is part of the United Kingdom. Covering the northern third of the island of Great Britain, mainland Scotland has a border with England to the southeast and is otherwise surrounded by the Atlantic Ocean to the north and west, the North Sea to the northeast and east, and the Irish Sea to the south. It also contains more than 790 islands, principally in the archipelagos of the Hebrides and the Northern Isles. Most of the population, including the capital Edinburgh, is concentrated in the Central Belt—the plain between the Scottish Highlands and the Southern Uplands—in the Scottish Lowlands. Scotland is divided into 32 administrative subdivisions or local authorities, known as council areas. Glasgow City is the largest council area in terms of population, with Highland being the largest in terms of area. Limited self-governing power, covering matters such as education, social services and roads and transportation, is devolved from the Scott ...

Gold
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental ( native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is ...

Julius Von Haast
Sir Johann Franz Julius von Haast (1 May 1822 – 16 August 1887) was a German-born New Zealand explorer, geologist, and founder of the Canterbury Museum in Christchurch. Early life Johann Franz Julius Haast was born on 1 May 1822 in Bonn, a town in the Kingdom of Prussia, to a merchant and his wife. As a child, he attended a local school but was also educated at a grammar school in Cologne. After completing his formal schooling, he then entered the University of Bonn, where he studied geology and mineralogy. However, he did not graduate. As a young man, he travelled throughout Europe before basing himself in Frankfurt, working in the trading of books and mineral samples collected on his journeys. On 26 October 1846, Haast married Antonia Schmitt at Frankfurt, Germany. The marriage, although unhappy, produced a son named Robert two years later. Haast was fluent in English and, in 1858, was contracted by a British shipping firm, A. Willis, Gann & Company, to report on the ...

James Hector
Sir James Hector (16 March 1834 – 6 November 1907) was a Scottish-New Zealand geologist, naturalist, and surgeon who accompanied the Palliser Expedition as a surgeon and geologist. He went on to have a lengthy career as a government employed man of science in New Zealand, and during this period he dominated the Colony's scientific institutions in a way that no single man has since. Early life He was born at 11 Danube Street in Stockbridge, Edinburgh the son of Alexander Hector WS and his wife, Margaret Macrostie. He attended the Edinburgh Academy from 1844 to 1845. At 14, he began articles as an actuary at his father's office. He joined University of Edinburgh as a medical student and received his medical degree in 1856 at the age of 22. Palliser expedition Shortly after receiving his medical degree, upon the recommendation of Sir Roderick Murchison – director-general of the British Geological Survey – Hector was appointed geologist on the Palliser Expedition under ...

Telephoto Lens
A telephoto lens, in photography and cinematography, is a specific type of a long-focus lens in which the physical length of the lens is shorter than the focal length. This is achieved by incorporating a special lens group known as a ''telephoto group'' that extends the light path to create a long-focus lens in a much shorter overall design. The angle of view and other effects of long-focus lenses are the same for telephoto lenses of the same specified focal length. Long-focal-length lenses are often informally referred to as ''telephoto lenses'', although this is technically incorrect: a telephoto lens specifically incorporates the telephoto group. Telephoto lenses are sometimes broken into the further sub-types of short telephoto (85–135 mm in 35 mm film format), medium telephoto: (135–300 mm in 35 mm film format) and super telephoto (over 300 mm in 35 mm film format) . Construction In contrast to a telephoto lens, for any given focal len ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fault Block
Fault blocks are very large blocks of rock, sometimes hundreds of kilometres in extent, created by tectonic and localized stresses in Earth's crust. Large areas of bedrock are broken up into blocks by faults. Blocks are characterized by relatively uniform lithology. The largest of these fault blocks are called crustal blocks. Large crustal blocks broken off from tectonic plates are called terranes. Those terranes which are the full thickness of the lithosphere are called microplates. Continent-sized blocks are called variously ''microcontinents, continental ribbons, H-blocks, extensional allochthons and outer highs.'' Because most stresses relate to the tectonic activity of moving plates, most motion between blocks is horizontal, that is parallel to the Earth's crust by strike-slip faults. However vertical movement of blocks produces much more dramatic results. Landforms (mountains, hills, ridges, lakes, valleys, etc.) are sometimes formed when the faults have a large v ...

Mountain Systems
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 geologically ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neotectonics
Neotectonics, a subdiscipline of tectonics, is the study of the motions and deformations of Earth's crust (geological and geomorphological processes) that are current or recent in geologic time. The term may also refer to the motions/deformations in question themselves. Geologists refer to the corresponding time-frame as the neotectonic period, and to the preceding time as the palaeotectonic period. Vladimir Obruchev coined the term ''neotectonics'' in his 1948 article, defining the field as "recent tectonic movements occurred in the upper part of Tertiary (Neogene) and in the Quaternary, which played an essential role in the origin of the contemporary topography". Since then geologists have disagreed as to how far back to date "geologically recent" time, with the common meaning being that neotectonics is the youngest, not yet finished stage in Earth tectonics. Some authors consider neotectonics to be basically synonymous with "active tectonics", while others date the start of the ...
