Olot Field volcan

The Quaternary Olot (Garrotxa) volcanic field occupies the NE corner of Spain south of the Pyrenees Mountains about 90 km NNE of Barcelona.

Introduction:

The Olot volcanic field consists of a large number of strombolian pyroclastic cones and associated alkali basaltic lava flows and is part of the NE Volcanic Province, which includes the Ampurdán and Selva areas to the SE. The pyroclastic cones are preferentially located at the intersection of E-W and NW-SE faults that cut sedimentary and metamorphic basement rocks. The latest dated eruption is a lava flow whose age was determined by thermoluminescence at 11,500 +/- 1100 years before present. More recent eruptions are possible but not confirmed (Mallarach 1993, pers. comm.). Source: Smithsonian GVP
