Reykjanes (sistema vulcanico)

Reykjanes

File di crateri · Iceland · 140 m

The snow-covered Reykjanes volcanic system forms the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level. It is the westernmost of a series of four closely spaced, NE-SW-trending, en-echelon fissure systems that extend diagonally across the Reykjanes Peninsula. Most of this system is covered by Holocene lavas, and eruptions occurred during the 13th century at several locations.

Sintesi geologica

The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level, comprises a broad area of postglacial basaltic crater rows and small shield volcanoes. The submarine Reykjaneshryggur volcanic system is contiguous with and is considered part of the Reykjanes volcanic system, which is the westernmost of a series of four closely-spaced en-echelon fissure systems that extend diagonally across the Reykjanes Peninsula. Most of the subaerial part of the system (also known as the Reykjanes/Svartsengi volcanic system) is covered by Holocene lavas. Subaerial eruptions have occurred in historical time during the 13th century at several locations on the NE-SW-trending fissure system, and numerous submarine eruptions dating back to the 12th century have been observed during historical time, some of which have formed ephemeral islands. Basaltic rocks of probable Holocene age have been recovered during dredging operations, and tephra deposits from earlier Holocene eruptions are preserved on the nearby Reykjanes Peninsula.
