Mineralogy
Mineralogy is a subject of geology specializing in the scientific study of the chemistry, crystal structure, and physical (including optical) properties of minerals and mineralized artifacts. Specific studies within mineralogy include the processes of mineral origin and formation, classification of minerals, their geographical distribution, as well as their utilization. History Early writing on mineralogy, especially on gemstones, comes from ancient Babylonia, the ancient Greco-Roman world, ancient and medieval China, and Sanskrit texts from ancient India and the ancient Islamic world. Books on the subject included the ''Naturalis Historia'' of Pliny the Elder, which not only described many different minerals but also explained many of their properties, and Kitab al Jawahir (Book of Precious Stones) by Persian scientist Al-Biruni. The German Renaissance specialist Georgius Agricola wrote works such as '' De re metallica'' (''On Metals'', 1556) and ''De Natura Fossilium'' ( ...

List Of Delaware River Tributaries
The watershed of the Delaware River drains an area of and encompasses 42 counties and 838 municipalities in five U.S. states—New York, New Jersey, Pennsylvania, Maryland, and Delaware.Philadelphia Water Department"Moving from Assessment to Protection...The Delaware River Watershed Source Water Protection Plan" (PWSID #1510001) (June 2007). Retrieved 17 July 2013. This total area constitutes approximately 0.4% of the land mass in the United States. The Delaware River rises in New York's Catskill Mountains flowing southward for 419 miles (674 km) into Delaware Bay where its waters enter the Atlantic Ocean near Cape May in New Jersey and Cape Henlopen in Delaware. There are 216 tributary streams and creeks—an estimated 14,057 miles of streams and creeks—in the watershed. The waters of the Delaware River's basin are used to sustain "fishing, transportation, power, cooling, recreation, and other industrial and residential purposes." While the watershed is home to 4.17 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pennsylvania Route 332
Pennsylvania Route 332 (PA 332) is a state highway in the U.S. state of Pennsylvania. The route runs from PA 263 in Hatboro, Montgomery County, east to PA 32 in Yardley, Bucks County. PA 332 runs through suburban areas to the north of Philadelphia, serving Warminster, Ivyland, Richboro, and Newtown. The route is two lanes wide most of its length, with the bypass around Newtown a four-lane divided highway. PA 332 intersects PA 132 in Warminster, PA 232 in Richboro, PA 413 and PA 532 in Newtown (all three run concurrently on the Newtown Bypass), and Interstate 295 (I-295) in Lower Makefield Township. What would become PA 332 between Newtown and Yardley was designated part of Legislative Route 252 in 1911. PA 332 was created in 1928 to run from PA 263 in Hatboro east to Ivyland with the road between Newtown and Yardley designated as part of PA 532. In 1937, PA 332 was extended to PA&n ...

Pennsylvania Route 532
Pennsylvania Route 532 (PA 532) is a state route located in the Philadelphia, Pennsylvania area. The route runs from an intersection with U.S. Route 1 (US 1) in Northeast Philadelphia north to an intersection with PA 32 in Washington Crossing near the Washington Crossing Bridge over the Delaware River. The route passes through developed areas in Northeast Philadelphia before heading north through suburban Bucks County, serving Feasterville, Holland, and Newtown before coming to Washington Crossing. Most of the portion of PA 532 south of Feasterville was chartered as the Bustleton and Somerton Turnpike in 1840. This road in Philadelphia became known as Bustleton Avenue in 1903. PA 532 was designated in 1928 to run from US 1 in Northeast Philadelphia to PA 32 in Yardley while PA 632 was designated on the route between Newtown and Washington Crossing. In 1946, PA 532 was rerouted to Washington Crossing, replacing PA 632, while the road between Newtown and Yardley became an exte ...

Mudstone
Mudstone, a type of mudrock, is a fine-grained sedimentary rock whose original constituents were clays or muds. Mudstone is distinguished from '' shale'' by its lack of fissility (parallel layering).Blatt, H., and R.J. Tracy, 1996, ''Petrology.'' New York, New York, W. H. Freeman, 2nd ed, 529 pp. The term ''mudstone'' is also used to describe carbonate rocks (limestone or dolomite) that are composed predominantly of carbonate mud. However, in most contexts, the term refers to siliciclastic mudstone, composed mostly of silicate minerals. The NASA Curiosity rover has found deposits of mudstone on Mars that contain organic substances such as propane, benzene and toluene. Definition There is not a single definition of mudstone that has gained general acceptance,Boggs 2006, p.143 though there is wide agreement that mudstones are fine-grained sedimentary rocks, composed mostly of silicate grains with a grain size less than . Individual grains this size are too small to be disting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Siltstone
Siltstone, also known as aleurolite, is a clastic sedimentary rock that is composed mostly of silt. It is a form of mudrock with a low clay mineral content, which can be distinguished from shale by its lack of fissility.Blatt ''et al.'' 1980, pp.381-382 Although its permeability and porosity is relatively low, siltstone is sometimes a tight gas reservoir rock, an unconventional reservoir for natural gas that requires hydraulic fracturing for economic gas production. Siltstone was prized in ancient Egypt for manufacturing statuary and cosmetic palettes. The siltstone quarried at Wadi Hammamat was a hard, fine-grained siltstone that resisted flaking and was almost ideal for such uses. Description There is not complete agreement on the definition of siltstone. One definition is that siltstone is mudrock ( clastic sedimentary rock containing at least 50% clay and silt) in which at least 2/3 of the clay and silt fraction is composed of silt-sized particles. Silt is defined a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arkose
Arkose () or arkosic sandstone is a detrital sedimentary rock, specifically a type of sandstone containing at least 25% feldspar. Arkosic sand is sand that is similarly rich in feldspar, and thus the potential precursor of arkose. Quartz is commonly the dominant mineral component, and some mica is often present. Apart from the mineral content, rock fragments may also be a significant component. Arkose usually contains small amounts of calcite cement, which causes it to effervesce (fizz) slightly in dilute hydrochloric acid; sometimes the cement also contains iron oxide. Arkose is typically grey to reddish in colour. The sand grains making up an arkose may range from fine to very coarse, but tend toward the coarser end of the scale. Fossils are rare in arkose, due to the depositional processes that form it, although bedding is frequently visible. Arkose is generally formed from the weathering of feldspar-rich igneous or metamorphic, most commonly granitic, rocks, which are p ...
