Tsaghkunyats Mountains
Tsaghkunyats Mountains (or Tsaghkunyats Ridge), hy, Ծաղկունյաց լեռնաշղթա (''Tsaghkunyats lernasheghta''), are a range of mountains in Armenia, mainly in the provinces of Kotayk and Aragatsotn. The range is of volcanic origin including many extinct volcanoes. It has a length of 42 km, stretched between Pambak Mountains near the village of Mijnatun at the north, and the right bank of Hrazdan River to the southeast. The highest peak of the Tsaghkunyats Mountains is Mount Teghenis near Tsaghkadzor, at 2851 meters. The range is formed by a volcanic field, containing Pleistocene-to-Holocene lava domes and cinder cones.Soviet Armenian Encyclopaedia, vol. 5, page 113 The area is a popular mountain resort with its spa towns and villages, including Tsaghkadzor, Hankavan, Bjni, Arzakan and Aghveran Aghveran ( hy, Աղվերան) is a mountain resort in the Kotayk Province of Armenia, within the municipality of Arzakan village, located to the north of Buzhakan ...

Armenia
Armenia (), , group=pron officially the Republic of Armenia,, is a landlocked country in the Armenian Highlands of Western Asia.The UNbr>classification of world regions places Armenia in Western Asia; the CIA World Factbook , , and ''Oxford Reference Online'' also place Armenia in Asia. It is a part of the Caucasus region; and is bordered by Turkey to the west, Georgia to the north, the Lachin corridor (under a Russian peacekeeping force) and Azerbaijan to the east, and Iran and the Azerbaijani exclave of Nakhchivan to the south. Yerevan is the capital, largest city and the financial center. Armenia is a unitary, multi-party, democratic nation-state with an ancient cultural heritage. The first Armenian state of Urartu was established in 860 BC, and by the 6th century BC it was replaced by the Satrapy of Armenia. The Kingdom of Armenia reached its height under Tigranes the Great in the 1st century BC and in the year 301 became the first state in the worl ...

Holocene
The Holocene ( ) is the current geological epoch. It began approximately 11,650 cal years Before Present (), after the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene has been identified with the current warm period, known as MIS 1. It is considered by some to be an interglacial period within the Pleistocene Epoch, called the Flandrian interglacial.Oxford University Press – Why Geography Matters: More Than Ever (book) – "Holocene Humanity" section https://books.google.com/books?id=7P0_sWIcBNsC The Holocene corresponds with the rapid proliferation, growth and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava Domes
In volcanology, a lava dome is a circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on Earth are lava dome forming. The geochemistry of lava domes can vary from basalt (e.g. Semeru, 1946) to rhyolite (e.g. Chaiten, 2010) although the majority are of intermediate composition (such as Santiaguito, dacite-andesite, present day) The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far. This high viscosity can be obtained in two ways: by high levels of silica in the magma, or by degassing of fluid magma. Since viscous basaltic and andesitic domes weather fast and easily break apart by further input of fluid lava, most of the preserved domes have high silica content and consist of rhyolite or dacite. Existence of lava domes has been suggested for some domed structures on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Fields
A volcanic field is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or a polygenetic volcanic field. Description Alexander von Humboldt observed in 1823 that geologically young volcanoes are not distributed uniformly across the Earth's surface, but tend to be clustered into specific regions. Young volcanoes are rarely found within cratons, but are characteristic of subduction zones, rift zones, or in ocean basins. Intraplate volcanoes are clustered along hotspot traces. Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. Scoria cones are particularly prone to cluster into volcanic fields, which are typically in diameter and consist of several tens ...

Bjni
Bjni ( hy, Բջնի), is a village in the Kotayk Province of Armenia. It is situated in a valley between canyon walls and a small river. The village is one of the prominent centers of education and culture of ancient and medieval Armenia. It is the birthplace of the 11th-century scholar Grigor Magistros. History The first recorded mention of the village was by the 5th- to 6th-century chronicler and historian Ghazar Parpetsi. In the 11th century, the lands of Bjni were passed to the Pahlavuni family and played a significant role in Armenian life during the Bagratuni Dynasty. Around this time, King Hovhannes-Smbat made the decision that the lands should become an Episcopal settlement. In 1066, the election for the Patriarch took place in Bjni. At the beginning of the 13th century, the lands were passed on to the Zakharyan family. A century later in the years 1387-1388 the Turko-Mongol conqueror Timur Lenk destroyed the village of Bjni.

Cinder Cone

Conical hills or mountains occur in different shap ... of loose pyroclastic fragments, such as volcanic clinkers, volcanic ash, or scoria that has been built around a volcanic vent. The pyroclastic fragments are formed by explosive eruptions or lava fountains from a single, typically cylindrical, vent. As the gas-charged lava is blown violently into the air, it breaks into small fragments that solidify and fall as either cinders, clinkers, or scoria around the vent to form a cone that often is symmetrical; with slopes between 30 and 40°; and a nearly circular ground plan. Most cinder cones have a bowl-shaped Volcanic crater, crater at the summit. Mechanics of eruption Cinder cones range in size from tens to hundreds of meter ...

Pleistocene
The Pleistocene ( , often referred to as the '' Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the t ...
