Macusani (volcano)

Macusani is a volcanic field in the Carabaya Province of Peru. It is formed by ignimbrites filling basins in the mountain range, with a total remnant volume of 430 cubic kilometres (100 cu mi). Some granitic stocks are also found there. A notable mineral found in the field is macusanite; indeed the field is notable for the unusual rock composition.

Macusani is not part of the principal volcanic arc, it belongs to the so-called "inner volcanic arc" of the eastern Cordillera. It is not clear why volcanism occurred in the Macusani region.
