Chemical analysis* of rocks from the Eyjafjöll 2010 eruptions - Níels Óskarsson
Soluble fluoride on volcanic ash and scoria from the eruption on Fimmvörðuháls
Soluble fluoride was measured in three samples from the eruption on Fimmvörðuháls:
The leachate is slightly acidic suggesting minor condensate from volcanic gases on grain surfaces. It is pointed out that the samples are coarse ash. Therefore, is has to be assumed that fluoride values will increase away from the volcano where the ash is more fine-grained and its surface are is larger.
Chemical composition of the Fimmvörðuháls 2010 lava
The composition belongs to the alkalic rock suite (.4% Ne in the Norm) at average titanium level which is characteristic for Eyjafjöll and different form the nearby High-Ti Mýrdalsjökull/Katla system.
