Ortiz Mountain Educational Preserve
The Ortiz Mountains are a mountain range in northern New Mexico, United States, in Santa Fe County, northeast of the Sandia Mountains and due north of the San Pedro Mountains. The Ortiz include Placer Peak, the highest peak in the range at 8,858 feet, Lone Mountain at 7,310 feet, Cedar Mountain at 7,041 feet, Cerro Chato at 6,965 feet, and the foothills known as the Los Lomas de la Bolsa. Geology The Ortiz Mountains are on the east side of the Rio Grande Rift, with the Santa Domingo Basin and Hagan Basin of the rift to their west, with the Sandia uplift to the southwest, and the Espanola Basin and the Estancia Basin to the east. They form part of the watershed boundary between the Rio Grande and the Pecos River. The Ortiz Mountains are part of the larger Ortiz porphyry belt of Santa Fe County, and consist of late Eocene to early Oligocene intrusive igneous rocks and their sedimentary host rock. Other members of the Ortiz porphyry belt are South Mountain, the San Pedro Mountains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vein (geology)
In geology, a vein is a distinct sheetlike body of crystallized minerals within a rock. Veins form when mineral constituents carried by an aqueous solution within the rock mass are deposited through precipitation. The hydraulic flow involved is usually due to hydrothermal circulation. Veins are classically thought of as being the ones in the body not the rock veins and arteries planar fractures in rocks, with the crystal growth occurring normal to the walls of the cavity, and the crystal protruding into open space. This certainly is the method for the formation of some veins. However, it is rare in geology for significant open space to remain open in large volumes of rock, especially several kilometers below the surface. Thus, there are two main mechanisms considered likely for the formation of veins: ''open-space filling'' and ''crack-seal growth''. Open space filling Open space filling is the hallmark of epithermal vein systems, such as a stockwork, in greisens or in cert ...

Mountain Ranges Of New Mexico
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 colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain a ...

Shrublands
Spring Park is a small area in London, England. It is within the London Borough of Bromley and the London Borough of Croydon, straddling the traditional Kent-Surrey border along The Beck. Spring Park is located north of Addington, west of West Wickham and south of Monks Orchard and Shirley.Willey, Russ. ''Chambers London Gazetter'', p. 467. History The area was historically known as Cold Harbour. Settlement began in the area in the 1830s at the instigation of the MP John Temple Leader, who employed the agricultural innovator Hewitt Davis to turn what was barren heathland into productive farmland. Large scale residential building began in the 1920s–1930s. The Shrublands council estate was constructed after the Second World War on compulsorily purchased land from the golf course. The area contains a small row of shops at the junction of Bridle Road and Broom Road. The Goat pub, which closed in 2017 following an attack on a local asylum seeker, re-opened in 2019 as The Apple Tre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artemisia (genus)
''Artemisia'' () is a large, diverse genus of plants with between 200 and 400 species belonging to the daisy family Asteraceae. Common names for various species in the genus include mugwort, wormwood, and sagebrush. ''Artemisia'' comprises hardy herbaceous plants and shrubs, which are known for the powerful chemical constituents in their essential oils. ''Artemisia'' species grow in temperate climates of both hemispheres, usually in dry or semiarid habitats. Notable species include '' A. vulgaris'' (common mugwort), '' A. tridentata'' (big sagebrush), '' A. annua'' (sagewort), '' A. absinthium'' (wormwood), ''A. dracunculus'' (tarragon), and '' A. abrotanum'' (southernwood). The leaves of many species are covered with white hairs. Most species have strong aromas and bitter tastes from terpenoids and sesquiterpene lactones, which discourage herbivory, and may have had a selective advantage. The small flowers are wind-pollinated. ''Artemisia'' species are used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adit
An adit (from Latin ''aditus'', entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins. Construction Adits are driven into the side of a hill or mountain, and are often used when an ore body is located inside the mountain but above the adjacent valley floor or coastal plain. In cases where the mineral vein outcrops at the surface, the adit may follow the lode or vein until it is worked out, in which case the adit is rarely straight. The use of adits for the extraction of ore is generally called drift mining. Adits can only be driven into a mine where the local topography permits. There will be no opportunity to drive an adit to a mine situated on a large flat plain, for instance. Also if the ground is weak, the cost of shoring up a long adit may outweigh its possible advantage ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
LAC Minerals
LAC Minerals was a Canadian mining company established in 1981 with extensive mineral holdings in North America and South America.

Heap Leaching
Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ore, whereas ''in situ'' mining lacks these liners and pulls pregnant solution up to obtain the minerals. Heap leaching is widely used in modern large-scale mining operations as it produces the desired concentrates at a lower cost compared to conventional processing methods such as flotation, agitation, and vat leaching. Additionally, dump leaching is an essential part of most copper mining operations and determines the quality grade of the produced material along with other factors Due to the profitability that the dump leaching has on the mining process, i.e. it can contribute substanti ...

Consolidated Gold Fields
Consolidated Gold Fields was a British gold-mining company. It was listed on the London Stock Exchange and was a constituent of the FTSE 100 Index until it was acquired by Hanson in 1988. History Consolidated Gold Fields of South Africa was founded in 1887 and incorporated in London to fund the newly discovered gold reefs in the Transvaal. By 1900 it had already started to diversify outside South Africa. After 1945 it acquired mines in the United States and Australia. Until the 1970s, it was predominantly a mining finance house receiving income from passive investments. In 1970 A.R.O. Williams O.B.E, who was then Managing Director, retired. After the 1970s it transformed itself into natural resource group concentrating on a relatively small number of minerals. The company had three major wholly owned subsidiaries: Amalgamated Roadstone Corporation, Gold fields Corporation and ARC America, both in the United States. By the late 1980s it was considering withdrawing from South Afr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
