Cay

Estratovolcán · Chile · 2090 m

Volcán Cay (upper left), is located east of Macá volcano (lower right) and NW of the town of Puerto Aisén.  The basaltic and dacitic stratovolcano has an explosion crater that is open to the east, and about a half dozen explosion craters and pyroclastic cones lie along a fissure trending SW of the summit.  Another 10 basaltic pyroclastic cones are located along second parallel fissure 5 km to the SE that is part of the major regional Liquiñe-Ofqui fault zone.

Resumen geológico

Volcán Cay, located E of Macá volcano and NW of the town of Puerto Aisén, is a basaltic to dacitic stratovolcano. An explosion crater is open to the E, and about a half dozen explosion craters and pyroclastic cones lie along a fissure trending SW of the summit. Another 10 basaltic pyroclastic cones are located along a second parallel fissure 5 km SE that is part of the major regional Liquiñe-Ofqui fault zone. These cones were considered to be Holocene by González-Ferrán (1995), but Naranjo and Stern (2004) found no evidence for Holocene tephra deposits.
