Tronador

成層火山 · Chile-Argentina · 3478m

The western side of glacier-covered Monte Tronador volcano overlies rugged granitic peaks of the Northern Patagonian Batholith in the foreground. Activity at the Tronador volcanic group, which straddles the Chile-Argentina border east of scenic Lake Todos los Santos, dates back to the early Pleistocene and ended during the mid-Pleistocene. The only possible Holocene activity in the volcano group took place SSE of Monte Tronador, forming the post-glacial Fonck cinder cone and lava flow.

地質学的概要

The Tronador volcanic group straddles the Chile-Argentina border east of scenic Lake Todos los Santos. Activity dates back to the early Pleistocene, and the most prominent part of the dominantly basaltic-to-andesitic complex is the prominent, glacier-covered Monte Tronador volcano, which formed in three stages during the mid-Pleistocene. The only possible Holocene activity took place SSE of Monte Tronador, where the Fonck cinder cone (also known as Cerro Volcanico) overlies rocks of the Steffen volcano group. The well-preserved cone was the source of a single andesitic lava flow that postdates the last glacial cycle dating back to 70,000-14,000 years ago and has variously been inferred to be of latest Pleistocene or Holocene age.

Wikipedia の要約

Tronador is an extinct stratovolcano in the southern Andes, located along the border between Argentina and Chile, near the Argentine city of Bariloche. The mountain was named Tronador by locals in reference to the sound of falling seracs. With an altitude of 3,470 metres (11,380 ft), Tronador stands more than 1,000 m above nearby mountains in the Andean massif, making it a popular mountaineering destination. Located inside two national parks, Nahuel Huapi in Argentina and Vicente Pérez Rosales in Chile, Tronador hosts a total of eight glaciers, which are currently retreating due to warming of the upper troposphere.
