Miniques

Stratovulcano · Chile · 5910 m

The broad Volcán Miñiques massif rises to the SE above Laguna Miñiques.  The 5910-m-high summit of the volcano is cut by three overlapping, E-W-trending craters.  Larger craters, partially filled by lava domes and flows, are located west and NE of the summit of the volcano, which is of late Pleistocene or Holocene age.  A prominent lava flow, not visible in this image, extends NW-ward from the summit to the lower flanks, separating Laguna Miñiques from Laguna Miscanti to the north.

Sintesi geologica

Volcán Miñiques is a large basaltic andesite to dacitic volcanic complex S of Laguna Miscanti and Laguna Miñiques. The summit is cut by three overlapping craters. Larger craters, partially filled by lava domes and flows, are located W and NE of the summit. The stratovolcano and lava-dome complex was considered to have been active from the Pliocene to the Holocene (González-Ferrán, 1995); de Silva (2007 pers. comm.) assigned it a possible Holocene age. A prominent lava flow extends NW from the summit to the lower flanks, separating Laguna Miñiques from Laguna Miscanti.
