👉 Volcanic plateau in the context of Big Raven Plateau

The Big Raven Plateau is an intermontane plateau in Cassiar Land District of northwestern British Columbia, Canada. It lies on the Tahltan Highland and is surrounded by several valleys, including those of Mess Creek, Kakiddi Creek, Chakima Creek, Walkout Creek and the Klastline River. The plateau is drained by many small streams that flow into these neighbouring valleys and, unlike the neighbouring valleys, it is relatively barren of vegetation. Stream erosion has resulted in the creation of canyons with intervening ridges on the eastern and western sides of the Big Raven Plateau. The plateau is in Mount Edziza Provincial Park, which is one of the largest provincial parks in British Columbia. Access to the Big Raven Plateau is mainly by aircraft or by a network of horse trails from surrounding roads.

The Big Raven Plateau is volcanic in origin, consisting mostly of basaltic lava flows of the Mount Edziza volcanic complex that were erupted in the last 7.5 million years. These lava flows are interbedded with rhyolite and trachyte which are in the form of rock fragments produced and ejected by explosive eruptions. The dominant feature on the Big Raven Plateau is Mount Edziza, an ice-covered stratovolcano reaching an elevation of 2,786 metres (9,140 feet). Its composition is more diverse, consisting of alkali basalt, hawaiite, trachybasalt, tristanite, mugearite, benmoreite, trachyte and rhyolite which are in the form of lava flows, lava domes and breccia. The Big Raven Plateau is subdivided into at least 10 geological formations, each being the product of a distinct period of volcanic activity.

Volcanic plateau in the context of Iceland

Iceland is a Nordic island country between the Arctic Ocean and the North Atlantic Ocean, located on the Mid-Atlantic Ridge between Europe and North America. It is culturally and politically linked with Europe and is the region's westernmost and most sparsely populated country. Its capital and largest city is Reykjavík, which is home to about 36% of the country's roughly 390,000 residents (excluding nearby towns/suburbs, which are separate municipalities). The official language of the country is Icelandic. Iceland is on a rift between tectonic plates, and its geologic activity includes geysers and frequent volcanic eruptions. The interior consists of a volcanic plateau with sand and lava fields, mountains and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite being at a latitude just south of the Arctic Circle. Its latitude and marine influence keep summers chilly, and most of its islands have a polar climate.

According to the Landnámabók, an ancient manuscript, the settlement of Iceland began in 874 AD, when the Norwegian chieftain Ingólfr Arnarson became the island's first permanent settler. In following centuries, Norwegians and to a lesser extent other Scandinavians, immigrated to Iceland, bringing with them thralls (i.e., slaves or serfs) of Gaelic origin. The island was governed as an independent commonwealth under the native parliament, the Althing, one of the world's oldest functioning legislative assemblies. After a period of civil strife, Iceland acceded to Norwegian rule in the 13th century. In 1397, Iceland followed Norway's integration into the Kalmar Union along with the kingdoms of Denmark and Sweden, coming under de facto Danish rule upon its dissolution in 1523. The Danish kingdom introduced Lutheranism by force in 1550, and the Treaty of Kiel formally ceded Iceland to Denmark in 1814.

Volcanic plateau in the context of Javakheti Plateau

Javakheti Plateau (Georgian: ჯავახეთის პლატო) is a volcanic plateau within the Caucasus Mountains that covers the Samtskhe-Javakheti region of Georgia, along the border with Turkey and Armenia. Its elevation is over 2,000 m.

Volcanic plateau in the context of Malwa Plateau

Malwa (IPA: [maːlʋaː]) is a historical region of west-central India occupying a plateau of volcanic origin. Geologically, the Malwa Plateau generally refers to the volcanic upland north of the Vindhya Range. Politically and administratively, it is also synonymous with the former state of Madhya Bharat which was later merged with Madhya Pradesh. At present the historical Malwa region includes districts of western Madhya Pradesh and parts of south-eastern Rajasthan. Sometimes the definition of Malwa is extended to include the Nimar region south of the Vindhyas.

The Malwa region had been a separate political unit from the time of the ancient Malava Kingdom, and has been ruled by several kingdoms and dynasties. Malwa continued to be an administrative division until 1947, when the Malwa Agency of British India was merged into Madhya Bharat (also known as Malwa Union) state of independent India.

Volcanic plateau in the context of Korazim Plateau

The Korazim Plateau (Hebrew: רמת כורזים, Ramat Korazim, also spelled Corazim) is a volcanic plateau, located in northern Israel. The plateau is bounded between by the Hula Valley in the north, Sea of Galilee in the south, the mountains of the Galilee to the west and by the Jordan River to the east. It is named after an ancient Jewish settlement also known as "Chorazin". The highest point is Filon Hill, which is 409 meters above sea level.

The plateau is home to a few Israeli communities, including Rosh Pinna, Hatzor HaGlilit and the Bedouin town of Tuba-Zangariyye. The plateau's rural settlements make part of the regional councils of Upper Galilee, Mevo'ot HaHermon and Emek HaYarden. Several important archaeological and historical sites are located on the plateau, including Tel Hazor, Daughters of Jacob Bridge, Mount of Beatitudes and Jubb Yussef. Historically the plateau also served as a transit region for the valleys to the north and south, and the heights to the east and west. Armies passed through the plateau towards the Golan during the Palestine Campaign of World War I in 1918, the 1948 Arab–Israeli war, Six Day War and Yom Kippur War.

Volcanic plateau in the context of North Island Volcanic Plateau

The North Island Volcanic Plateau (often called the Central Plateau and occasionally the Waimarino Plateau) is a volcanic plateau covering much of central North Island of New Zealand with volcanoes, lava plateaus, and crater lakes. It contains the Taupō caldera complex, Ōkataina caldera complex and Tongariro Volcanic Centre resulting in it being currently the most frequently active and productive area of silicic volcanism on Earth. New Zealand is part of the Pacific Ring of Fire.

Volcanic plateau in the context of Pajarito Plateau

The Pajarito Plateau is a volcanic plateau in north central New Mexico, United States. The plateau, part of the Jemez Mountains, is bounded on the west by the Sierra de los Valles, the range forming the east rim of the Valles Caldera, and on the east by the Puye escarpment, which rises about 300 to 400 feet (90 to 100 m) above the Rio Grande valley about a mile (1.6 km) west of the river. The Rio Grande passes through White Rock Canyon to the southeast, and the Caja del Rio (Cerros del Rio) across the river is sometimes regarded as part of the plateau. The plateau is occupied by several notable entities, including Bandelier National Monument, the town of Los Alamos and its remote suburb White Rock, and Los Alamos National Laboratory. Elevations range from about 5,600 feet (1,700 meters) at the river to about 7,800 feet (2,400 meters) where the plateau merges into the mountain range.

The Pajarito Plateau is primarily composed of Bandelier Tuff, a voluminous deposit of volcanic tuff laid down in an explosive eruption — in this case, a pair of eruptions from the nearby Valles Caldera. The two ignimbrite-forming eruptions occurred about 1.6 million and 1.2 million years ago and ejected about 300 cubic kilometers of rock each. The orange-pink rock formations constituting the resulting ignimbrites are known as the Otowi and Tshirege Members of the Bandelier tuff. The tuff lies on top of a volcanic field, exposed to the east, which used to be continuous with the Caja del Rio (now across the Rio Grande).
