Mesoperthite
Perthite is used to describe an intergrowth of two feldspars: a host grain of potassium-rich alkali feldspar (near K-feldspar, KAlSi3O8, in composition) includes exsolved lamellae or irregular intergrowths of sodic alkali feldspar (near albite, NaAlSi3O8, in composition). Typically, the host grain is orthoclase or microcline, and the lamellae are albite. If sodic feldspar is the dominant phase, the result is an antiperthite and where the feldspars are in roughly equal proportions the result is a mesoperthite. The intergrowth forms by exsolution due to cooling of a grain of alkali feldspar with a composition intermediate between K-feldspar and albite. There is complete solid solution between albite and K-feldspar at temperatures near 700 °C and pressures like those within the crust of the Earth, but a miscibility gap is present at lower temperatures. If an alkali feldspar grain with an intermediate composition cools slowly enough, K-rich and more Na-rich feldspar domains separ ...

Belknap Mountains
The Belknap Mountains are a small mountain range in the Lakes Region of New Hampshire in the United States. The range lies in the towns of Gilford, Gilmanton, and Alton in Belknap County. The highest peak, Belknap Mountain, with an elevation of above sea level, is the highest point in Belknap County. Belknap Mountain State Forest covers the central part of the range, including the summit and slopes of Belknap Mountain. The range extends for approximately in an arc that begins at New Hampshire Route 11A in Gilford and runs south, then curves east through the northern end of Gilmanton, before ending in the town of Alton, where it overlooks Alton Bay of Lake Winnipesaukee. The named summits in the range, from northwest to southeast, are Mount Rowe (), Gunstock Mountain (), Belknap Mountain, Straightback Mountain (), and Mount Major ().

Pemigewasset Wilderness
The Pemigewasset Wilderness is a federally designated Wilderness Area in the heart of New Hampshire's White Mountains. It is a part of the White Mountain National Forest. It is New Hampshire's largest wilderness area. The Wilderness Area consists of the upper watershed of the East Branch of the Pemigewasset River, and includes the Franconia, Twin, Zealand, and Hancock mountain ranges, but excludes the summits of the ranges and the trail along them. As a result of the region's rugged character, the Pemigewasset Wilderness is a popular recreation area; its large trail network receives heavy use, in the form of hiking, cross-country skiing, and others, throughout the year. The area is also noted for its ecological recovery from the logging era of the late nineteenth and early twentieth centuries. After years of unchecked clear-cutting, during which the zone had the largest logging railroad system in the White Mountains, the area's inclusion in the White Mountain National Fores ...

Crawford Notch
Crawford Notch is a major pass through the White Mountains of New Hampshire, located in Hart's Location. Roughly half of that town is contained in Crawford Notch State Park. The high point of the notch, at approximately above sea level, is at the southern end of the town of Carroll, near the Crawford Depot train station and Saco Lake, the source of the Saco River, which flows southward through the steep-sided notch. North of the high point of the notch, Crawford Brook flows more gently northwest to the Ammonoosuc River, a tributary of the Connecticut River. The notch is traversed by U.S. Route 302, which closely follows the Saco River southeast to North Conway and less closely follows the Ammonoosuc River northwest to Littleton. History Originally called White Mountain Notch, it became known to European settlers when found by Timothy Nash in 1771. The 1772 boundaries of Hart's Grant reflected its shape. It was named for the Crawford family, who were trail-builders and h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Franconia Notch
Franconia Notch (elev. ) is a major mountain pass through the White Mountains of New Hampshire. Dominated by Cannon Mountain to the west and Mount Lafayette to the east, it lies principally within Franconia Notch State Park and is traversed by the Franconia Notch Parkway (Interstate 93 and U.S. Route 3). The parkway required a special act of Congress to sidestep design standards for the Interstate highway system because it is only one lane in each direction. Kimberly A. Jarvis, ''From the Mountains to the Sea: Protecting Nature in Postwar New Hampshire'' (University of Massachusetts Press, 2020online review/ref> The notch was home to the Old Man of the Mountain, a rock formation which collapsed in 2003 but whose profile remains a symbol of the state of New Hampshire. The notch is located primarily in the town of Franconia but extends south into Lincoln. It is bordered to the east by Franconia Ridge, comprising Mount Lafayette (), Mount Lincoln (), and Little Haystack Mountai ...

White Mountains (New Hampshire)
The White Mountains are a mountain range covering about a quarter of the state of New Hampshire and a small portion of western Maine in the United States. They are part of the northern Appalachian Mountains and the most rugged mountains in New England. The range is heavily visited due to its proximity to Boston, New York City, and Montreal. Most of the area is public land, including the White Mountain National Forest and a number of state parks. Its most famous mountain is Mount Washington, which is the highest peak in the Northeastern U.S. and for 76 years held the record for fastest surface wind gust in the world ( in 1934). Mount Washington is part of a line of summits, the Presidential Range, that are named after U.S. presidents and other prominent Americans. The White Mountains also include the Franconia Range, Sandwich Range, Carter-Moriah Range and Kinsman Range in New Hampshire, and the Mahoosuc Range straddling the border between it and Maine. In all, there are 48 peak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old Man Of The Mountain
The Old Man of the Mountain, also called the Great Stone Face and the Profile, was a series of five granite cliff ledges on Cannon Mountain in Franconia, New Hampshire, United States, that appeared to be the jagged profile of a human face when viewed from the north. The rock formation, above Profile Lake, was tall and wide. The Old Man of the Mountain is called "Stone Face" by the Abenaki and is a symbol within their culture. It is also a symbol to the Mohawk people. The first written mention of the Old Man was in 1805. It became a landmark and a cultural icon for the state of New Hampshire.

Biotite
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula . It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite. Biotite was regarded as a mineral ''species'' by the International Mineralogical Association until 1998, when its status was changed to a mineral ''group''. The term ''biotite'' is still used to describe unanalysed dark micas in the field. Biotite was named by J.F.L. Hausmann in 1847 in honor of the French physicist Jean-Baptiste Biot, who performed early research into the many optical properties of mica. Members of the biotite group are sheet silicates. Iron, magnesium, aluminium, silicon, oxygen, and hydrogen form sheets that are weakly bound together by potassium ions. The term "iron mica" is sometimes used for iron-rich biotite, but the term also refers to a flaky micaceous form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
