Greenstone (archaeology)
Greenstone is a common generic term for valuable, green-hued minerals and metamorphosed igneous rocks and stones which early cultures used in the fashioning of hardstone carvings such as jewelry, statuettes, ritual tools, and various other artifacts. Greenstone artifacts may be made of greenschist, chlorastrolite, serpentine, omphacite, chrysoprase, olivine, nephrite, chloromelanite among other green-hued minerals. The term also includes jade and jadeite, although these are perhaps more frequently identified by these latter terms. The greenish hue of these rocks generally derives from the presence of minerals such as chlorite, hornblende, or epidote.Kipfer (2000, p.218) Greenstone minerals were presumably selected for their color rather than their chemical composition. In archaeology therefore, having a loosely applied general term is at least partially influenced by the observation that ancient cultures often used and considered these various green-hued materials as interchan ...

Greenstone Building
The Greenstone Building, officially the Greenstone Government of Canada Building, and sometimes known as the Greenstone Government Building, is located on Franklin (50th) Avenue in downtown Yellowknife, Northwest Territories, Canada. It is a four-storey building faced in stone, completed and opened in 2005. Within are the local offices of 16 federal government agencies. Prior to the building's construction they were scattered in different buildings around the city. The name comes from greenstone, a rock found in great quantity in the area, from which the gold that led to Yellowknife's development was extracted. The building reflects that past in two other ways. Its interior stair tower is sided in slanted boards that recall the mineshaft towers still standing, and the location of a prominent local fault beneath the building is marked on the lobby floor. It was designed by the Edmonton firm of Manasc Isaac to be environmentally sustainable. Its central atrium has a curta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenstone (software)
Greenstone is a suite of software tools for building and distributing digital library collections on the Internet or CD-ROM.

Greenstone River
The Greenstone River is a river in the Otago Region of New Zealand. It arises as the McKellar Branch in the Ailsa Mountains and as the Pass Burn in the Thomson Mountains, and joins the Caples River to flow into upper Lake Wakatipu. It is probably named because greenstone was found in the area. The Greenstone Track follows the river north along the McKellar Branch to Lake McKellar, joining the Hollyford Track. Another track follows the Pass Burn and reaches North Mavora Lake. See also * List of rivers of New Zealand *Greenstone and Caples Tracks The Greenstone and Caples Tracks form a tramping (hiking) circuit which is located in the South Island of New Zealand. Each track can be completed by itself and are linked by the McKellar Saddle while the loop also links to several other track ...

Jade
Jade is a mineral used as jewellery or for ornaments. It is typically green, although may be yellow or white. Jade can refer to either of two different silicate minerals: nephrite (a silicate of calcium and magnesium in the amphibole group of minerals), or jadeite (a silicate of sodium and aluminium in the pyroxene group of minerals). Jade is well known for its ornamental use in East Asian, South Asian, and Southeast Asian art. It is commonly used in Latin America, such as Mexico and Guatemala. The use of jade in Mesoamerica for symbolic and ideological ritual was influenced by its rarity and value among pre-Columbian Mesoamerican cultures, such as the Olmecs, the Maya, and other ancient civilizations of the Valley of Mexico. Etymology The English word ''jade'' is derived (via French and Latin 'flanks, kidney area') from the Spanish term (first recorded in 1565) or 'loin stone', from its reputed efficacy in curing ailments of the loins and kidneys. ''Nephrite'' is der ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elvan
Elvan is a name used in Cornwall and Devon for the native varieties of quartz-porphyry. They are dispersed irregularly in the Devonian series of rocks and some of them make very fine building stones (e.g. Pentewan stone, Polyphant stone and Catacleuse stone). Greenstone is another name for this stone and it is often used for parts of buildings such as doorways so they can be finely carved. Most of the elvan quarries are now disused. Others are quarried in bulk for aggregates commonly used for road-building. More precisely there are two types of rock in this category: one is "white elvan" and the other is "blue elvan". "White elvans" are a group of fine-grained, acid igneous rocks, while "blue elvans" or "greenstones" are various unusual basic igneous rocks. "White elvan" comes from various different locations and is often known as Pentewan stone (or by other names based on the location). Some older descriptions of building stones have called "white elvans" limestone, e.g. in stu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenschist
Greenschists are metamorphic rocks that formed under the lowest temperatures and pressures usually produced by regional metamorphism, typically and 2–10 kilobars (). Greenschists commonly have an abundance of green minerals such as chlorite, serpentine, and epidote, and platy minerals such as muscovite and platy serpentine. The platiness gives the rock schistosity (a tendency to split into layers.) Other common minerals include quartz, orthoclase, talc, carbonate minerals and amphibole (actinolite). Greenschist is a general field petrologic term for metamorphic or altered mafic volcanic rock. In Europe, the term ''prasinite'' is sometimes used. A ''greenstone'' is sometimes a greenschist but can also be rock types without any schistosity, especially metabasalt (spilite). However, basalts may remain quite black if primary pyroxene does not revert to chlorite or actinolite. To qualify for the name a rock must also exhibit schistosity or some foliation or layering.
