Anthracite coal

Anthracite (Greek Ανθρακίτης, literally "a form of coal", from Anthrax [Άνθραξ], coal) is a hard, compact variety of mineral coal that has a high luster. It has the highest carbon count and contains the fewest impurities of all coals, despite its lower caloric content. Anthracite coal is the highest of the metamorphic rank, in which the carbon content is between 92% and 98%. The term is applied to those varieties of coal which do not give off tarry or other hydrocarbon vapours when heated below their point of ignition. Anthracite ignites with diffic ...

Anthracite is similar in appearance to the mineraloid jet, and is sometimes used to imitate it. Physically, anthracite differs from ordinary bituminous coal by its greater hardness, higher density, 1.3-1.4, and luster, the latter being often semi-metallic with a somewhat brownish reflection. It contains a high percentage of fixed carbon and a low percentage of volatile matter. It is also free from included soft or fibrous notches and does not soil the fingers when rubbed. Anthracitization is the transform ...

The Appalachian Mountains are a vast system of North American mountains, partly in Canada, but mostly in the United States, extending as a zone, from 100 to 300 miles wide, running from Newfoundland and Labrador, Canada, 1500 miles south-westward to central Alabama in the United States, although the northernmost mainland portion ends at the Gaspé Peninsula of Quebec. The system is divided into a series of ranges, with the individual mountains averaging around 3000 ft. The highest of the group is Mt. Mitchell in North Carolina (2,040m ...

The whole system may be divided into three great sections: the Northern, from Newfoundland to the Hudson river; the Central, from the Hudson Valley to that of New river (Great Kanawha), in Virginia and West Virginia; and the Southern, from New river onwards. The northern section includes the Shickshock Mountains and Notre Dame Range in Quebec, scattered elevations in Maine, the White Mountains and the Green Mountains; the central comprises, besides various minor groups, the Valley Ridges between the Front of the Alleghen ...

The primary standard pronunciation of the range is with a long-A, as "app-uh-LAY-chan" or [æ.pəˈle.tʃən]. The alternative pronunciation, with a short-A, "app-uh-LATCH-an" or [æ.pəˈlæ.tʃən], is often used east of the range in the Piedmont region, such as in North Carolina. The short-A pronunciation is used for Appalachian State University of Boone, North Carolina. It turns out that the shor ...

Main article: Geology of the Appalachians The Appalachians are old mountains. A look at rocks exposed in today's Appalachian mountains reveals elongated belts of folded and thrust faulted marine sedimentary rocks, volcanic rocks and slivers of ancient ocean floor, which provides strong evidence that these rocks were deformed during plate collision. The birth of the Appalachian ranges, some 680 million years ago, marks the first of several mountain building plate collisions that culminated in the construction of the supercontine ...

The Appalachian belt includes, with the ranges enumerated above, the plateaus sloping southward to the Atlantic Ocean in New England, and south-eastward to the border of the coastal plain through the central and southern Atlantic states; and on the north-west, the Allegheny and Cumberland plateaus declining toward the Great Lakes and the interior plains. A remarkable feature of the belt is the longitudinal chain of broad valleys--the Great Appalachian Valley--which, in the southerly sections divides the mountain system into two subequal port ...

The largest fields of anthracite coal in the United States are found in Northeastern Pennsylvania called the Coal Region, where there are 7 billion short tons (6.4 petagrams) of minable reserves. Deposits at Crested Butte, Colorado were mined historically. Anthracite deposits of an estimated 3 billion short tons (2.7 Pg) in Alaska have never been mined. Anthracites of newer, tertiary or cretaceous age, are found in the Crow's Nest part of the Rocky Mountains in C ...

Pottsville, Pennsylvania anthracite coal history began in 1790 with the discovery of coal made by the hunter Necho Allen in what is called the Coal Region. Legend has it that Allen fell asleep at the base of the Broad Mountain and woke to the sight of a large fire. His campfire had ignited an outcropping of anthracite coal. By 1795, an anthracite fired iron furnace was established on the Schuylkill River. Anthracite was first experimentally burned as a fuel on February 11, 1808 by Judge Jeese Fell in Wilkes-Barre, Pennsylvania on a op ...
