Volcán Tequila is an eroded andesitic-dacitic volcano surrounded by a series of older flank rhyolitic lava domes and obsidian flows ranging from 0.9 to 0.23 Ma in age. A prominent summit spine, similar to that at Sangangüey, has been dated at 0.21 Ma. The spine occupies a large summit crater open to the NE, which was formed by erosion. After the cessation of activity at the central vent, andesitic lava flows were erupted from vents on the flanks, and a chain of lava domes was formed on the SE flank. At least a dozen cinder cones younger than the central volcano were erupted along a WNW-trending line SW and south of the volcano. These were roughly estimated on the basis of morphology to be older than 40,000 years.
