Kandovan, Osku
Kandovan ( fa, كندوان, also romanized as Kandovān and Kandavān; also known as Kanvān) is an ancient village in Sahand Rural District in the Central District of Osku County, East Azerbaijan Province, northwestern Iran. It is situated in the foothills of Mount Sahand, near the city of Osku. At the 2006 census, the village population was 601, in 168 families. The village exemplifies manmade cliff dwellings which are still inhabited. The troglodyte homes, excavated inside volcanic rocks similar to dwellings in the Turkish region of Cappadocia, are locally called ''Karaan''.Hashemi, S., 2013. ''The Magnificence of Civilization in Depths of Ground (A Review of Underground Structures in Iran – Past to Present)'', Shadrang Printing and Publishing Co., Tehran. Karaans were cut into non-welded ignimbrites, also called "ash-flow tuffs," of Mount Sahand. The cone form of the houses is the result of the erosion of ignimbrite layers consisting of porous, round and angular pumice t ...

List Of Sovereign States
The following is a list providing an overview of sovereign states around the world with information on their status and recognition of their sovereignty. The 206 listed states can be divided into three categories based on membership within the United Nations System: 193 UN member states, 2 UN General Assembly non-member observer states, and 11 other states. The ''sovereignty dispute'' column indicates states having undisputed sovereignty (188 states, of which there are 187 UN member states and 1 UN General Assembly non-member observer state), states having disputed sovereignty (16 states, of which there are 6 UN member states, 1 UN General Assembly non-member observer state, and 9 de facto states), and states having a special political status (2 states, both in free association with New Zealand). Compiling a list such as this can be a complicated and controversial process, as there is no definition that is binding on all the members of the community of nations concerni ...

Iran
Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Turkey to the west, by Azerbaijan and Armenia to the northwest, by the Caspian Sea and Turkmenistan to the north, by Afghanistan and Pakistan to the east, and by the Gulf of Oman and the Persian Gulf to the south. It covers an area of , making it the 17th-largest country. Iran has a population of 86 million, making it the 17th-most populous country in the world, and the second-largest in the Middle East. Its largest cities, in descending order, are the capital Tehran, Mashhad, Isfahan, Karaj, Shiraz, and Tabriz. The country is home to one of the world's oldest civilizations, beginning with the formation of the Elamite kingdoms in the fourth millennium BC. It was first unified by the Medes, an ancient Iranian people, in the seventh century BC, and reached its territorial height in the sixth century BC, when Cyrus the Great fo ...

Pyroclastic Flow
A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of but is capable of reaching speeds up to . The gases and tephra can reach temperatures of about . Pyroclastic flows are the most deadly of all volcanic hazards and are produced as a result of certain explosive eruptions; they normally touch the ground and hurtle downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. Origin of term The word ''pyroclast'' is derived from the Greek (''pýr''), meaning "fire", and (''klastós''), meaning "broken in pieces". A name for pyroclastic flows which glow red in the dark is (French, "burning cloud"); this was notably used to describe the disastrous 1902 eruption of Mount Pelée on Martinique, a French ...

Pumice
Pumice (), called pumicite in its powdered or dust form, is a volcanic rock that consists of highly vesicular rough-textured volcanic glass, which may or may not contain crystals. It is typically light-colored. Scoria is another vesicular volcanic rock that differs from pumice in having larger vesicles, thicker vesicle walls, and being dark colored and denser.Jackson, J.A., J. Mehl, and K. Neuendorf (2005) ''Glossary of Geology'' American Geological Institute, Alexandria, Virginia. 800 pp. McPhie, J., M. Doyle, and R. Allen (1993) ''Volcanic Textures A guide to the interpretation of textures in volcanic rocks'' Centre for Ore Deposit and Exploration Studies, University of Tasmania, Hobart, Tasmania..198 pp. Pumice is created when super-heated, highly pressurized rock is violently ejected from a volcano. The unusual foamy configuration of pumice happens because of simultaneous rapid cooling and rapid depressurization. The depressurization creates bubbles by lowering the solubi ...

Sahand
Sahand ( fa, سهند), is a massive, heavily eroded stratovolcano in East Azerbaijan Province, northwestern Iran. At , it is the highest mountain in the province of East Azarbaijan. Sahand is one of the highest mountains in Iranian Azerbaijan, in addition to being an important dormant volcano in the country. The Sahand mountains are directly south of Tabriz, the highest peak of which is Kamal at an elevation of . Approximately 17 peaks can be accounted for as being over in height. Due to the presence of a variety of flora and fauna, the Sahand mountains are known as the bride of mountains in Iran. The absolute dating of Sahand rocks indicates that this volcano has been sporadically active from 12 million years ago up to almost 0.14 million years ago. Sahand is made chiefly of dacite and associated felsic rocks. Winter sports Sahand Ski Resort is on the northern foothills of the mountain and near the city of Tabriz.

Tuff
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Following ejection and deposition, the ash is lithified into a solid rock. Rock that contains greater than 75% ash is considered tuff, while rock containing 25% to 75% ash is described as tuffaceous (for example, ''tuffaceous sandstone''). Tuff composed of sandy volcanic material can be referred to as volcanic sandstone. Tuff is a relatively soft rock, so it has been used for construction since ancient times. Because it is common in Italy, the Romans used it often for construction. The Rapa Nui people used it to make most of the ''moai'' statues on Easter Island. Tuff can be classified as either igneous or sedimentary rock. It is usually studied in the context of igneous petrology, although it is sometimes described using sedimentological terms. Tuff is often erroneously called tufa in guidebooks and in television programmes. Volcanic ash The material that is expelled in a volcanic ...

Ignimbrite
Ignimbrite is a type of volcanic rock, consisting of hardened tuff. Ignimbrites form from the deposits of pyroclastic flows, which are a hot suspension of particles and gases flowing rapidly from a volcano, driven by being denser than the surrounding atmosphere. New Zealand geologist Patrick Marshall (1869-1950) coined the term ''ignimbrite'' from the Latin ''igni-'' [fire] and ''imbri-'' [rain]. Ignimbrites are made of a very poorly sorted mixture of volcanic ash (or tuff when Lithification, lithified) and pumice lapilli, commonly with scattered lithic fragments. The ash is composed of glass shards and crystal fragments. Ignimbrites may be loose and unconsolidated, or lithified (solidified) rock called lapilli-tuff. Near the volcanic source, ignimbrites often contain thick accumulations of lithic blocks, and distally, many show meter-thick accumulations of rounded cobbles of pumice. Ignimbrites may be white, grey, pink, beige, brown, or black depending on their composition and d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cappadocia
Cappadocia or Capadocia (; tr, Kapadokya), is a historical region in Central Anatolia, Turkey. It largely is in the provinces Nevşehir, Kayseri, Aksaray, Kırşehir, Sivas and Niğde. According to Herodotus, in the time of the Ionian Revolt (499 BC), the Cappadocians were reported as occupying a region from Mount Taurus to the vicinity of the Euxine (Black Sea). Cappadocia, in this sense, was bounded in the south by the chain of the Taurus Mountains that separate it from Cilicia, to the east by the upper Euphrates, to the north by Pontus, and to the west by Lycaonia and eastern Galatia. Van Dam, R. ''Kingdom of Snow: Roman rule and Greek culture in Cappadocia.'' Philadelphia: University of Pennsylvania Press, 2002, p.13 The name, traditionally used in Christian sources throughout history, continues in use as an international Tourism in Turkey, tourism concept to define a region of exceptional natural wonders, in particular characterized by fairy chimneys and a unique ...

Romanize
Romanization or romanisation, in linguistics, is the conversion of text from a different writing system to the Roman (Latin) script, or a system for doing so. Methods of romanization include transliteration, for representing written text, and transcription, for representing the spoken word, and combinations of both. Transcription methods can be subdivided into ''phonemic transcription'', which records the phonemes or units of semantic meaning in speech, and more strict ''phonetic transcription'', which records speech sounds with precision. Methods There are many consistent or standardized romanization systems. They can be classified by their characteristics. A particular system’s characteristics may make it better-suited for various, sometimes contradictory applications, including document retrieval, linguistic analysis, easy readability, faithful representation of pronunciation. * Source, or donor language – A system may be tailored to romanize text from a particular lan ...
