Volcanic pumices from Azorean volcanic islands Fogo and Faial. Samples collected by Adriano Pimentel and donated for analysis by Dunan Pirrie. The goal was to see if we could image crystals, crystal fragments or vesicles. Images will be correlated with SEM-EDS and a publication is due soon. To get this dataset, please contact fairdata-pas@gtk.fi. Preview dataset found at https://doi.org/10.23729/70838421-fe0b-4b37-b2e4-388e87f19d49
