Azores Islands

All the specimens on this page were found by myself during two visits, in 2007 and 2023, to São Miguel, the largest island of the archipelago. There are two locations that are interesting enough for collecting microminerals, the Pumice Quarry near Ribeira Grande - to which I got permission to collect without any problem - and the Vale das Lombadas, a natural occurrence with many xenolithic syenites in the main rock, that contain a large variety of mineral species - only in the micro range, never in larger crystals.
