3He/4He ratios in and around Teide volcano, Tenerife, Canary Islands, Spain
Helium-3 emission spatial distribution in and around Teide volcano, Tenerife, Canary Islands, has a quite different pattern from other stratovolcanoes which show usually a decreased trend for the 3He/ 4He with respect to distance from the summit crater. This finding might be related to the volcano-t...

| Resumo: | Helium-3 emission spatial distribution in and around Teide volcano, Tenerife, Canary Islands, has a quite different pattern from other stratovolcanoes which show usually a decreased trend for the 3He/ 4He with respect to distance from the summit crater. This finding might be related to the volcano-tectonic setting differences between subduction-type and oceanic island-type statrovolcanoes. Radiogenic helium p ro d u c tio n is a q u ite significant process fo r the d ilu tio n o f uprising deep-m antle fluids in and a ro u n d subduction-type stratovolcanoes while it can be almost negligible for polygenetic volcanoes at oceanic islands |
