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.
