지질학적 요약
The conical Nevado de Longaví is a late-Pleistocene to Holocene, dominantly andesitic stratovolcano constructed over a basement of Tertiary volcaniclastic and granitic rocks. Two edifice-collapse events modified the E and SW flanks of a pre-Holocene edifice, and Holocene activity has been concentrated at the summit and on the E flanks. Andesitic-to-dacitic lava domes occupy the summit region. The latest eruptions produced a lava dome in the upper part of the collapse scarp and summit region that partially collapsed to the E, forming block-and-ash flow deposits. Fumarolic activity has been reported.
Wikipedia 요약
영어 요약Nevado de Longaví is a volcano in the Andes of central Chile. The 3,242 m (10,636 ft) high volcano lies in the Linares Province, which is part of the Maule Region. It features a summit crater and several parasitic vents. The volcano is constructed principally from lava flows. Two collapses of the edifice have carved collapse scars into the volcano, one on the eastern slope known as Lomas Limpias and another on the southwestern slope known as Los Bueye. The volcano features a glacier and the Achibueno and Blanco rivers originate on the mountain.
