Lanin Volcano, Argentina
Lanín volcano is a compound stratocone rising to 12,
293 feet (3,747m).
The youngest three units have been constructed since the Middle-Late
Pleistocene.
Compositionally, volcanic rocks from the volcano are mainly
basalts/basaltic andesites and dacites with scarce intermediate types.
Postglacial pyroclastic deposits are also silicic and confirm
a sharp bimodality of the magmas.
It has no historic eruptions.
An eruption in 560 +/- 150 AD is based on radiocarbon dating.
The following stamp to commemorate Argentina highway 40 was
issued August 25th, 2007.
