Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east–west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east–west. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valley, Appalac ...

Long Range Mountains
The Long Range Mountains are a series of mountains along the west coast of the Canadian island of Newfoundland. The long range mountains form the northernmost section of the Appalachian mountain chain on the eastern seaboard of North America. Mapping of the Great Northern Peninsula was first done in the early 1900s by Mattie Mitchell, Mi'kmaq chieftain, guide and explorer. In 2003, it was announced that the International Appalachian Trail would be extended through the Long Range Mountains. A portion of the trail opened in 2006. Description The Great Northern Peninsula of Western Newfoundland contains the Highlands, the largest external basement massif of the Grenville Orogeny in the Appalachian Orogen. This Precambrian basement is known as the Long Range Inlier, Long Range Complex or Basement Gneiss Complex, consisting of quartz-feldspar gneisses and granites that are up to 1,550 million years in age. The Long Range dikes are mafic in composition and have a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newfoundland (island)
Newfoundland (, ; french: link=no, Terre-Neuve, ; ) is a large island off the east coast of the North American mainland and the most populous part of the Canadian province of Newfoundland and Labrador. It has 29 percent of the province's land area. The island is separated from the Labrador Peninsula by the Strait of Belle Isle and from Cape Breton Island by the Cabot Strait. It blocks the mouth of the Saint Lawrence River, creating the Gulf of Saint Lawrence, the world's largest estuary. Newfoundland's nearest neighbour is the French overseas collectivity of Saint Pierre and Miquelon. With an area of , Newfoundland is the world's 16th-largest island, Canada's fourth-largest island, and the largest Canadian island outside the North. The provincial capital, St. John's, is located on the southeastern coast of the island; Cape Spear, just south of the capital, is the easternmost point of North America, excluding Greenland. It is common to consider all directly neighbouring i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ophiolite
An ophiolite is a section of Earth's oceanic crust and the underlying upper mantle that has been uplifted and exposed above sea level and often emplaced onto continental crustal rocks. The Greek word ὄφις, ''ophis'' (''snake'') is found in the name of ophiolites, because of the superficial texture of some of them. Serpentinite especially evokes a snakeskin. The suffix ''lite'' from the Greek ''lithos'' means "stone". Some ophiolites have a green color. The origin of these rocks, present in many mountainous massifs, remained uncertain until the advent of plate tectonic theory. Their great significance relates to their occurrence within mountain belts such as the Alps and the Himalayas, where they document the existence of former ocean basins that have now been consumed by subduction. This insight was one of the founding pillars of plate tectonics, and ophiolites have always played a central role in plate tectonic theory and the interpretation of ancient mountain belts. Pse ...

Peridotite
Peridotite ( ) is a dense, coarse-grained igneous rock consisting mostly of the silicate minerals olivine and pyroxene. Peridotite is ultramafic, as the rock contains less than 45% silica. It is high in magnesium (Mg2+), reflecting the high proportions of magnesium-rich olivine, with appreciable iron. Peridotite is derived from Earth's mantle, either as solid blocks and fragments, or as crystals accumulated from magmas that formed in the mantle. The compositions of peridotites from these layered igneous complexes vary widely, reflecting the relative proportions of pyroxenes, chromite, plagioclase, and amphibole. Peridotite is the dominant rock of the upper part of Earth's mantle. The compositions of peridotite nodules found in certain basalts are of special interest along with diamond pipes (kimberlite), because they provide samples of Earth's mantle brought up from depths ranging from about 30 km to 200 km or more. Some of the nodules preserve isotope ratios of osm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stephenville, Newfoundland And Labrador
Stephenville (Canada 2021 Census population 6540) is a town in Newfoundland and Labrador, Canada, on the west coast of the island of Newfoundland.

Corner Brook, Newfoundland And Labrador
Corner Brook ( 2021 population: 19,333 CA 29,762) is a city located on the west coast of the island of Newfoundland in the province of Newfoundland and Labrador, Canada. Corner Brook is the fifth largest settlement in Newfoundland and Labrador.

International Appalachian Trail
The International Appalachian Trail (IAT; french: Sentier international des Appalaches, SIA) was originally a hiking trail which ran from Katahdin Woods and Waters National Monument, in Maine, through New Brunswick, to the Gaspé Peninsula of Quebec, after which it followed a ferry route to Newfoundland, and then continued to the northern-easternmost point of the Appalachian Mountains at Belle Isle, Newfoundland and Labrador. As of July 2020, there are widely geographically dispersed IAT-branded walking trails in Greenland, Iceland, Norway, Sweden, Denmark, Scotland, Northern Ireland, Ireland, Isle of Man, Wales, England, Spain, Portugal, and Morocco. History The IAT was proposed in 1994 by Richard Anderson, a Maine fisheries biologist, with plans to traverse the portions of the Appalachian Mountains in Maine, New Brunswick, and Quebec that the Appalachian Trail did not cover. Following route selection, construction of the trail took place through the late 1990s. The first pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
