Gastre Fault
The Gastre Fault Zone (GFZ) is a NW-SE striking dextral Jurassic Gastre Fault System (cf. Rapela & Pankhurst, 1992) in Central Patagonia, Argentina. From a tentative correlation of the fault zone with the similarly NW-SE trend, it was termed ‘Gastre Fault Zone’ or ‘Gastre-Purén Fault Zone’ to the Lanalhue Fault Zone in Chile by early works. However, in later works it is shown that this correlation is incorrect. Since the lake ‘Lago Lanalhue’, is located on the fault trace and shows a NW-SE-elongated shape, ‘Lanalhue Fault Zone (LFZ)’ stands as appropriate name for the here discussed fault zone. The Mocha-Villarrica Fault Zone is the NW-SE trending fault responsible for the alignment of Villarrica, Quetrupillán and Lanín Lanín is an ice-clad, cone-shaped stratovolcano on the border of Argentina and Chile. It forms part of two national parks: Lanín in Argentina and Villarrica in Chile. It is a symbol of the Argentine province of Neuquén, being part of i ...

Villarrica (volcano)
Villarrica ( ) ( es, Volcán Villarrica, arn, Ruka Pillañ) is one of Chile's most active volcanoes, rising above the Lake Villarrica, lake and Villarrica, Chile, town of the same name, south of Santiago. It is also known as Rucapillán, a Mapudungun, Mapuche word meaning "Pillan, great spirit's house" or " the demon's house". It is the westernmost of three large stratovolcanoes that trend northwest to southeast obliquely perpendicular to the Andes, Andean chain along the Mocha-Villarrica Fault Zone, and along with Quetrupillán and the Chilean portion of Lanín, are protected within Villarrica National Park. Guided ascents are popular during summer months. Villarrica, with its lava of basaltic-andesitic composition, is one of a small number worldwide known to have an active (but in this case intermittent) lava lake within its volcanic crater, crater. The volcano usually generates strombolian eruptions with ejection of incandescent pyroclasts and lava flows. Rainfall plus melted ...

Quetrupillán
Quetrupillán ("blunted", "mutilated"; also known as Ketropillán) is a stratovolcano located in Los Ríos Region of Chile. It is situated between Villarrica and Lanín volcanoes, within Villarrica National Park. Geologically, Quetrupillán is located in a tectonic basement block between the main traces of Liquiñe-Ofqui Fault (to the west) and Reigolil-Pirihueico Fault (to the east). The volcano consists of one stratovolcano with a summit caldera, and is constructed within a field of smaller centres and a larger caldera. It was active during the late Pleistocene; some large eruptions occurred during the Holocene as well. Geology and geography The volcano is situated in the Curarrehue, Pucón and Panguipulli municipalities of the Cautín and Valdivia provinces. Towns close to Quetrupillán are Catripulli, Currarehue and Puesco. It is considered Chile's 21st most dangerous volcano.

Lanín
Lanín is an ice-clad, cone-shaped stratovolcano on the border of Argentina and Chile. It forms part of two national parks: Lanín in Argentina and Villarrica in Chile. It is a symbol of the Argentine province of Neuquén, being part of its flag and its anthem. Although the date of its last eruption is not known, it is estimated to have occurred within the last 10,000 years. Following the 1906 Valparaíso earthquake a local newspaper reported the volcano to have erupted, but a work published in 1917 by Karl Sapper disputed this.Luis E. Lara, José A. Naranjo and Hugo Moreno, 2004Lanín volcano (39.5°S), Southern Andes: geology and morphostructural evolution '' Revista Geológica de Chile'' vol. 31. The ascent is regulated by the management of Argentine National Parks and the Argentine National Gendarmerie and is technically relatively simple but has a much higher level of exposure than the neighbouring volcanoes.

Geology Of Neuquén Province
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...
