Diabase
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French , and ultimately from the Greek 'act of crossing over, transition', whereas the name ''dolerite'' comes from the French , from the Greek 'deceitful, deceptive', because it was easily confused with diorite. Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landmarks In Oregon
A landmark is a recognizable natural or artificial feature used for navigation, a feature that stands out from its near environment and is often visible from long distances. In modern-day use, the term can also be applied to smaller structures or features that have become local or national symbols. Etymology In Old English, the word ''landmearc'' (from ''land'' + ''mearc'' (mark)) was used to describe a boundary marker, an "object set up to mark the boundaries of a kingdom, estate, etc." Starting around 1560, this interpretation of "landmark" was replaced by a more general one. A landmark became a "conspicuous object in a landscape". A ''landmark'' literally meant a geographic feature used by explorers and others to find their way back to their departure point, or through an area. For example, Table Mountain near Cape Town, South Africa, was used as a landmark to help sailors navigate around the southern tip of Africa during the Age of Exploration. Artificial structures are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oregon Ballot Measure 37 (2004)
Oregon Ballot Measure 37 was a controversial land-use ballot initiative that passed in the U.S. state of Oregon in 2004 and is now codified as Oregon Revised Statutes (ORS) 195.305. Measure 37 has figured prominently in debates about the rights of property owners versus the public's right to enforce environmental and other land use regulations. Voters passed Measure 49 in 2007, substantially reducing the impact of Measure 37.Bethany R. Berger, What Owners Want and Governments Do: Lessons from the Oregon Experiment, 78 Fordham L. Rev. 1291 (2009), https://ssrn.com/abstract=1408343 Content of the proposal The law enacted by Measure 37 allows property owners whose property value is reduced by environmental or other land use regulations to claim compensation from state or local government. If the government fails to compensate a claimant within two years of the claim, the law allows the claimant to use the property under only the regulations in place at the time he/she purchased t ...

Ken Kesey
Ken Elton Kesey (; September 17, 1935 – November 10, 2001) was an American novelist, essayist and Counterculture of the 1960s, countercultural figure. He considered himself a link between the Beat Generation of the 1950s and the hippies of the 1960s. Kesey was born in La Junta, Colorado, and grew up in Springfield, Oregon, graduating from the University of Oregon in 1957. He began writing ''One Flew Over the Cuckoo's Nest (novel), One Flew Over the Cuckoo's Nest'' in 1960 after completing a graduate fellowship in creative writing at Stanford University; the novel was an immediate commercial and critical success when published two years later. During this period, Kesey was used by the Central Intelligence Agency, CIA (supposedly without his knowledge) in the Project MKULTRA involving hallucinogenic drugs (including mescaline and LSD), which was done to try to make people insane to put them under the control of interrogators. After ''One Flew Over the Cuckoo's Nest'' was pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz
Quartz is a hard, crystalline mineral composed of silica (silicon dioxide). The Atom, atoms are linked in a continuous framework of SiO4 silicon–oxygen Tetrahedral molecular geometry, tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of Silicon dioxide, SiO2. Quartz is, therefore, classified structurally as a Silicate mineral#Tectosilicates, framework silicate mineral and compositionally as an oxide mineral. Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar. Quartz exists in two forms, the normal α-quartz and the high-temperature β-quartz, both of which are chiral. The transformation from α-quartz to β-quartz takes place abruptly at . Since the transformation is accompanied by a significant change in volume, it can easily induce microfracturing of ceramics or rocks passing through this temperature threshold. There are many different varieties of quartz, several of which are classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesolite
Mesolite is a tectosilicate mineral with formula . It is a member of the zeolite group and the natrolite subgroup, also resembling natrolite in appearance. Mesolite crystallizes in the orthorhombic system and typically forms fibrous, acicular prismatic crystals or masses. Radiating sprays of needlelike crystals are not uncommon. It is vitreous in luster and clear to white in color. It has a Mohs hardness of 5 to 5.5 and a low specific gravity of 2.2 to 2.4. The refractive indices are nα=1.505 nβ=1.505 nγ=1.506. Occurrence It was first described in 1816 for an occurrence in the Cyclopean Islands near Catania, Sicily. From the Greek ''mesos'', "middle", as its composition lies between natrolite and scolecite. Like other zeolites, mesolite occurs as void fillings in amygdaloidal basalt also in andesites and hydrothermal veins.

Malachite
Malachite () is a copper Carbonate mineral, carbonate hydroxide mineral, with the chemical formula, formula Basic copper carbonate, Cu2CO3(OH)2. This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmite, stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation. Individual crystals are rare, but occur as slender to Acicular (crystal habit), acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur. Etymology and history The stone's name derives (via , , and Middle English ''melochites'') from Greek language, Greek Μολοχίτης λίθος ''molochites lithos'', "mallow-green stone", from μολόχη ''molochē'', variant of μαλάχη ''malāchē'', "mallow". The mineral was given this name due to its resemblance to the leaves of the Malva, mallow plant. Copper (Cu2+) g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jasper
Jasper, an aggregate of microgranular quartz and/or cryptocrystalline chalcedony and other mineral phases, is an opaque, impure variety of silica, usually red, yellow, brown or green in color; and rarely blue. The common red color is due to iron(III) inclusions. Jasper breaks with a smooth surface and is used for ornamentation or as a gemstone. It can be highly polished and is used for items such as vases, seals, and snuff boxes. The density of jasper is typically 2.5 to 2.9 g/cm3. Jaspillite is a banded-iron-formation rock that often has distinctive bands of jasper. Etymology and history The name means "spotted or speckled stone," and is derived via Old French (variant of Anglo-Norman ''jaspe'') and Afroasiatic language (cf. Hebrew language">Hebrew ' , Akkadian ''yashupu''). This Semitic etymology is believed to be unrelated to that of the English given name Persian origin, though the Persian word for the mineral jasper is also ''yashum'' ( :fa:یشم">ی ...

Heulandite
Heulandite is the name of a series of tectosilicate minerals of the zeolite group. Prior to 1997, heulandite was recognized as a mineral species, but a reclassification in 1997 by the International Mineralogical Association changed it to a series name, with the mineral species being named: * Heulandite-Ca * Heulandite-Na * Heulandite-K * Heulandite-Sr * Heulandite-Ba (described in 2002). Heulandite-Ca, the most common of these, is a hydrous calcium and aluminium silicate with the formula . Small amounts of sodium and potassium are usually present replacing part of the calcium. Strontium replaces calcium in the heulandite-Sr variety. The appropriate species name depends on the dominant element. The species are visually indistinguishable, and the series name heulandite is still used whenever testing has not been performed. Crystallography and properties Crystals are monoclinic. They may have a characteristic coffin-shaped habit, but may also form simple rhombic prisms. Freque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
