| The Apastepeque volcanic field north of the city of San Vicente consists of a dense cluster of about two dozen chemically diverse Holocene volcanic vents, including lava domes, cinder cones, and maars. Andesitic-to-dacitic lava domes were emplaced in some vents following dacitic pumice eruptions. After the end of these more siliceous eruptions, a series of basaltic cinder cones was formed. Some of the basaltic eruptions concluded with the formation of steep-walled maars up to 100 m deep, some now occupied by lakes, such as Laguna de Apastepeque and Laguna Chalchuapán. | |||
