Origin
Lokon volcano on Sulawesi, Indonesia. The particles were collected at a few kilometers from the volcano within 24 hours after a minor eruption
Main constituent
silica glass, plagioclase, magnetite
Practical significance
interpretation of remote sensing data. Analogues of other planets' atmospheric dust, and dust in comets, asteroids, and circumstellar shells
