Inwood Formation (New York)
Tuckahoe marble (also known as Inwood and Westchester marble) is a type of marble found in southern New York state and western Connecticut. Part of the Inwood Formation of the Manhattan Prong, it dates from the Late Cambrian to the Early Ordovician ages (~484 ma ago). It was first quarried on a large scale commercially in the village of Tuckahoe, New York. Deposits are also found in the Inwood area of Manhattan, New York City, in Eastchester, New York, and extending southward to parts of the Bronx, such as Kingsbridge, Mott Haven, Melrose and Tremont and Marble Hill. Other locations in Westchester County include Ossining, Hastings, and Thornwood. Description and geology Tuckahoe marble is a high quality marble first quarried on a large commercial scale in 1822 in the village of Tuckahoe in Westchester County. The marble is from the larger Inwood Formation or deposit, which stretches northeasterly from mid-Manhattan through southern Westchester and into western Connect ...

Bronx River
The Bronx River (), approximately long, flows through southeast New York in the United States and drains an area of . It is named after colonial settler Jonas Bronck. Besides the Hutchinson River, the Bronx River is the only fresh water river in New York City.; all the other rivers within the city are straits and tidal estuaries, and the tidal lower reach of the Hudson River. It originally rose in what is now the Kensico Reservoir, in Westchester County north of New York City. With the construction of the Kensico Dam in 1885, however, the river was cut off from its natural headwaters and today a small tributary stream serves as its source. The Bronx River flows south past White Plains, then south-southwest through the northern suburbs in New York, passing through Edgemont, Tuckahoe, Eastchester, and Bronxville. It forms the border between the large cities of Yonkers and Mount Vernon, and flows into the northern end of The Bronx, where it divides East Bronx from West Bronx, s ...

War Of 1812
The War of 1812 (18 June 1812 – 17 February 1815) was fought by the United States of America and its indigenous allies against the United Kingdom and its allies in British North America, with limited participation by Spain in Florida. It began when the United States declared war on 18 June 1812 and, although peace terms were agreed upon in the December 1814 Treaty of Ghent, did not officially end until the peace treaty was ratified by Congress on 17 February 1815. Tensions originated in long-standing differences over territorial expansion in North America and British support for Native American tribes who opposed US colonial settlement in the Northwest Territory. These escalated in 1807 after the Royal Navy began enforcing tighter restrictions on American trade with France and press-ganged men they claimed as British subjects, even those with American citizenship certificates. Opinion in the US was split on how to respond, and although majorities in both the House and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Oxidation
Redox (reduction–oxidation, , ) is a type of chemical reaction in which the oxidation states of substrate change. Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a decrease in the oxidation state. There are two classes of redox reactions: * ''Electron-transfer'' – Only one (usually) electron flows from the reducing agent to the oxidant. This type of redox reaction is often discussed in terms of redox couples and electrode potentials. * ''Atom transfer'' – An atom transfers from one substrate to another. For example, in the rusting of iron, the oxidation state of iron atoms increases as the iron converts to an oxide, and simultaneously the oxidation state of oxygen decreases as it accepts electrons released by the iron. Although oxidation reactions are commonly associated with the formation of oxides, other chemical species can serve the same function. In hydrogenation, C=C (and other) bonds ar ...

Pyrite
The mineral pyrite (), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula Iron, FeSulfur, S2 (iron (II) disulfide). Pyrite is the most abundant sulfide mineral. Pyrite's metallic Luster (mineralogy), luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of ''fool's gold''. The color has also led to the nicknames ''brass'', ''brazzle'', and ''Brazil'', primarily used to refer to pyrite found in coal. The name ''pyrite'' is derived from the Greek language, Greek (), 'stone or mineral which strikes fire', in turn from (), 'fire'. In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. By Georgius Agricola's time, , the term had become a generic term for all of the pyrite group, sulfide minerals. Pyrite is usua ...

Hematite
Hematite (), also spelled as haematite, is a common iron oxide compound with the formula, Fe2O3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of . It has the same crystal structure as corundum () and ilmenite (). With this it forms a complete solid solution at temperatures above . Hematite naturally occurs in black to steel or silver-gray, brown to reddish-brown, or red colors. It is mined as an important ore mineral of iron. It is electrically conductive. Hematite varieties include ''kidney ore'', ''martite'' (pseudomorphs after magnetite), ''iron rose'' and ''specularite'' (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is not only harder than pure iron, but also much more brittle. Maghemite is a polymorph of hematite (γ-) with the same chemical formula, but with a spinel structure like magnetite. Large deposits of hematite are found in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Calcite
Calcite is a Carbonate minerals, carbonate mineral and the most stable Polymorphism (materials science), polymorph of calcium carbonate (CaCO3). It is a very common mineral, particularly as a component of limestone. Calcite defines hardness 3 on the Mohs scale of mineral hardness, based on Scratch hardness, scratch hardness comparison. Large calcite crystals are used in optical equipment, and limestone composed mostly of calcite has numerous uses. Other polymorphs of calcium carbonate are the minerals aragonite and vaterite. Aragonite will change to calcite over timescales of days or less at temperatures exceeding 300 °C, and vaterite is even less stable. Etymology Calcite is derived from the German ''Calcit'', a term from the 19th century that came from the Latin word for Lime (material), lime, ''calx'' (genitive calcis) with the suffix "-ite" used to name minerals. It is thus etymologically related to chalk. When applied by archaeology, archaeologists and stone trade pr ...

Dolomite (mineral)
Dolomite () is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone. History As stated by Nicolas-Théodore de Saussure the mineral dolomite was probably first described by Carl Linnaeus in 1768. In 1791, it was described as a rock by the French naturalist and geologist Déodat Gratet de Dolomieu (1750–1801), first in buildings of the old city of Rome, and later as samples collected in the mountains now known as the Dolomite Alps of northern Italy. Nicolas-Théodore de Saussure first named the mineral (after Dolomieu) in March 1792. Properties The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. Unless it ...

Thornwood, New York
Thornwood is a hamlet (unincorporated community), census-designated place (CDP), and postal designation (with zip code 10594) in the town of Mount Pleasant in Westchester County, New York, United States. The population was 3,759 at the 2010 census. History In 1891, Lewis Smadback started a very successful development at what is now Thornwood. The village of Sherman Park was incorporated in 1906 and the name was changed to Hillside in 1909. The village was dissolved in 1914, when Thornwood took its current name and became a hamlet within the Town of Mount Pleasant. It is possible that Thornwood is a derivative of "Hawthorne's Woods," since Hawthorne is an adjacent hamlet. Another possibility is Thornwood is named after an area in Glasgow, Scotland. Thornwood once had a large and thriving Westchester marble quarry near its heart, the intersection of Route 141 and Kensico Road (known as Four Corners). Dating back to 1845, the quarry supplied white marble which helped build St. ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
