(Redirected from Osorno Volcano). Osorno Volcano is a 2,652-metre (8,701 ft) tall conical stratovolcano lying between Osorno Province and Llanquihue Province, in Los Lagos Region of Chile.he upper slopes of the volcano are almost entirely covered in glaciers despite its very modest altitude and latitude, sustained by the substantial snowfall in the very moist maritime climate of the region. Osorno sits on top of a 250,000-year-old eroded stratovolcano, La Picada, with a 6-km-wide caldera.
Scoria cones, also known as cinder cones, are the most common type of volcano. They are also the smallest type, with heights generally less than 300 meters.They can occur as discrete volcanoes on basaltic lava fields, or as parasitic cones generated by flank eruptions on shield volcanoes and stratovolcanoes.Scoria cones are composed almost wholly of ejected basaltic tephra.The tephra is most commonly of lapilli size, although bomb-size fragments and lava spatter may also be present. The tephra fragments typically contain abundant gas bubbles (vesicles), giving the lapilli and bombs a cindery (or scoriaceous) appearance.hey can occur as discrete volcanoes on basaltic lava fields, or as parasitic cones generated by flank eruptions on shield volcanoes and stratovolcanoes.
