Adamellite
Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Because of its coloring, it is often confused with granite, but whereas granite contains more than 20% quartz, quartz monzonite is only 5–20% quartz. Rock with less than five percent quartz is classified as monzonite. A rock with more alkali feldspar is a syenite whereas one with more plagioclase is a quartz diorite.Classification of Igneous Rocks The fine grained [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Cod
Cape Cod is a peninsula extending into the Atlantic Ocean from the southeastern corner of mainland Massachusetts, in the northeastern United States. Its historic, maritime character and ample beaches attract heavy tourism during the summer months. The name Cape Cod, coined in 1602 by Bartholomew Gosnold, is the ninth oldest English place-name in the U.S. As defined by the Cape Cod Commission's enabling legislation, Cape Cod is conterminous with Barnstable County, Massachusetts. It extends from Provincetown in the northeast to Woods Hole in the southwest, and is bordered by Plymouth to the northwest. The Cape is divided into fifteen towns, several of which are in turn made up of multiple named villages. Cape Cod forms the southern boundary of the Gulf of Maine, which extends north-eastward to Nova Scotia. Since 1914, most of Cape Cod has been separated from the mainland by the Cape Cod Canal. The canal cuts roughly across the base of the peninsula, though small portions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rock
Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano. In other words, it differs from other igneous rock by being of volcanic origin. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "volcaniclastics," and these are technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mount Cardigan
Mount Cardigan is a prominent bare-rock summit in the towns of Orange and Alexandria in western New Hampshire, USA. While its peak is only above sea level, it has extensive areas of bare granite ledges and alpine scrub, giving it the feel to hikers of a much higher mountain. Most of the summit area was denuded by devastating forest fires in 1855. The Civilian Conservation Corps helped to develop the alpine ski trail network still in use today on the east side of the mountain. The mountain is set in the Cardigan Mountain State Park. The Cardigan Lodge, operated by the Appalachian Mountain Club since 1934, is located to the east at the foot of the mountain, and is often used as a base for day hikes in and around the mountain. Many schools from around New England have overnight field trips to the mountain during the autumn and spring months.. The mountain is also a popular destination for Boy Scout troops.

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 ...

Kinsman Mountain
Kinsman Mountain is a mountain located in Grafton County, New Hampshire. It is named after Nathan Kinsman, an early resident of Easton, New Hampshire, and is part of the Kinsman Range of the White Mountains. To the northeast, Kinsman is connected by The Cannon Balls ridge to Cannon Mountain. The west side of Kinsman drains into Reel and Slide Brooks, thence into the Ham Branch of the Gale River, the Gale River, Ammonoosuc River, Connecticut River, and into Long Island Sound in Connecticut. The east side drains into Cascade Brook, thence into the Pemigewasset River, the Merrimack River, and into the Gulf of Maine in Massachusetts. The south face drains into Eliza Brook, thence into Harvard Brook, another tributary of the Pemigewasset. The Appalachian Mountain Club considers both North and South Kinsman to be "four-thousand footers" because the divide between them gives the former more than of topographic prominence. South Kinsman is the sixth most prominent of the White M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Porphyry Copper
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic fluids. Successive envelopes of hydrothermal alteration typically enclose a core of disseminated ore minerals in often stockwork-forming hairline fractures and veins. Because of their large volume, porphyry orebodies can be economic from copper concentrations as low as 0.15% copper and can have economic amounts of by-products such as molybdenum, silver, and gold. In some mines, those metals are the main product. The first mining of low-grade copper porphyry deposits from large open pits coincided roughly with the introduction of steam shovels, the construction of railroads, and a surge ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to crea ...
