Abstract
Las islas Columbretes constituyen un pequeño archipiélago, formado por numerosos islotes, restos de la parte emergida de volcanes. Dos de esos volcanes tienen composición básica: el volcán de Columbrete Grande y el volcán de Navarrete. Los dos son tuff-rings de aproximadamente un kilómetro de diámetro, el primero de los cuales se ha formado en, al menos, tres fases eruptivas. Los cráteres del volcán de Columbrete Grande se alinean con el volcán de Navarrete, definiendo una dirección de actividad volcánica de composición básica, única en el archipiélago.
The Columbretes Islands constitute a small archipelago, formed by numerous islets, remains of the emerged part of volcanoes. Two of these volcanoes have a basic composition: the Columbrete Grande volcano and the Navarrete volcano. Both are tuff-rings of about one kilometer in diameter, the first of which has been formed in at least three eruptive phases. The craters of the Columbrete Grande volcano are aligned with the Navarrete volcano, defining a direction of volcanic activity of basic composition, unique in the archipelago.
