Mount Aragats ((アルメニア語:Արագած)) is a complex volcano in Armenia. One of the highest points in the Armenian Highlands, Aragats is the highest in present-day Republic of Armenia. It was active during multiple phases in the Pleistocene. Petroglyphs have been discovered around the volcano. ==Etymology and names== According to Armenian tradition, Aragats originates from the words Արա ''Ara'' + գահ ''gah'', which translates to "Ara's throne". Ara refers to the legendary hero Ara the Beautiful. Another name for the mountain is the Turkic ''Alagöz''. It was used widely from the settlement of Turkic peoples in the region until the 20th century in European, Russian, and early Soviet sources (Алагёз). A variant of the word, ''Alagyaz'' (Ալագյազ) was used by Armenians and is still sometimes used in the colloquial. A folk song from Shirak composed by Komitas is titled ''Alagyaz''. ==Geography and geology== Situated northwest of Yerevan, Aragats is a large volcano with numerous fissure vents and adventive cones. Numerous large lava flows descend from the volcano and are constrained in age between middle Pleistocene and 3000BCE. The summit crater is cut by a long line of cones which generated possibly Holocene-age lahars and lava flows. The volcanic system covers an area of 5000km2 and is one of the largest in the region. More recent activity in flank centres occurred in Tirinkatar (0.48-0.61 Ma), Kakavasar, (0.52-0.54 Ma) and Ashtarak (0.58 Ma), as well as Jrbazhan in the summit area (0.52 Ma). The magmas feeding Aragats are unusually hot for arc-derived magmas, resulting in long and voluminous lava flows. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Mount Aragats」の詳細全文を読む スポンサード リンク
