Volcano Puyehue Ash Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks Collecting

Volcanic Ash sample Raw Minerals Lapilli Pumice Lava Bombs Stones Rocks for Collection.
Rare collection of Cordon Caulle fissure volcanic Ash Pumice fine white from the Mount Puyehue's eruption Volcano in June 11, 2011. Extremely fine grained.
This material was collected in Argentina shortly after the eruption.

Volcanic ash consists of small tephra, which are bits of pulverized rock and glass created by volcanic eruptions, less than 2 millimetres (0.1 inch) in diameter . Ash is created when the usually violent nature of an eruption involving steam results in the magma and solid rock surrounding the vent being torn into particles of clay to sand size.
Every ash samples is labelled and bagged in a vial with cap (mm 44 x 10), so thay can easily be removed if required for study under a microscope.
As with all volcanic ash, the material should be handled with care and not inhaled.


Puyehue and Cordón Caulle are two coalescing volcanic buildings located in the Andes mountain range in southern Chile that form a mountain massif in the Puyehue National Park, in the Andean province of Lago Ranco (Río Bueno and Puyehue communes), in southern Chile. In Vulcanology this group is known as the Puyehue-Cordón Caulle volcanic complex (PCCVC). Four volcanoes make up the volcanic group or complex: the Cordillera Nevada caldera, the Mencheca Pliocene volcano, the Cordón Caulle fissure cracks and the Puyehue stratovolcano. Puyehue is located in the south-east, Cordón Caulle in the center, and the Cordillera Nevada, which owes its name to its often snow-covered appearance from the relatively densely populated Central Chilean valley, is located at the north-western end. The massif lies between two lakes, Lake Ranco in the north and Lake Puyehue in the south.
The Puyehue-Cordon Caulle has a height of 2,240 meters above sea level. It is surrounded by a volcanic sandy plateau strewn with numerous fumaroles, sulphites and thermal springs of considerable geothermal importance. Its caldera of about 2 km wide is covered with snow most of the year. Its name derives from the Mapudungun language in which Puye stands for "fishy stream" and Hue "place".
The Cordillera Nevada is a 9-kilometer wide semicircular caldera and corresponds to the remains of a collapsed volcano. The Puyehue volcano is a stratovolcano located at the southeastern end of the Cordón Caulle, just east of the main fault zone of the Liquiñe-Ofqui fault zone. Its cone houses a 2.4 km wide crater and the Puyehue volcanism products cover an approximate area of 160 sq km.
Like most of the stratovolcanoes of the so-called southern volcanic zone, part of the volcanic belt, the volcanic complex of the Puyehue-Cordon Caulle has developed over the last 300,000 years. The older parts of the Cordillera Nevada caldera and the Mencheca volcano also reflect the older Pliocene or early Pleistocene activities.
There are several eruptions in historical times: among the most recent, Cordón Caulle erupted shortly after the earthquake of Valdivia in 1960, the largest recorded earthquake in history.
After the end of the 1960 eruption, Cordón Caulle remained relatively quiet compared to the first half of the 20th century. On 2 March 1972 there was a report of an eruption west of Bariloche in Argentina. Starting from 4 June 2011, after more than fifty years of quiescence, it has reawakened again with a violent and spectacular eruption. Approximately 3,500 people were evacuated from nearby areas, while a cloud of ash reached a height of 12,000 meters, then falling back to the city of Bariloche, Argentina, where the local airport was closed and also followed other airports to Buenos Aires and even in Melbourne, Australia.
It is not given for sure, but the first known historical eruption should date to 1759.

Available on our website, besides ashes, pumice and bombs, also various volcanic rocks, such as Apache Teardrops, sulfur, obsidian, tuff, crystal chalk, etc.
