Origin
El Chichon volcano in Mexico. The particles were collected at a few kilometers from the vent within 24 hours after an eruption in 1982
Main constituent
volcanic silicate ash
Practical significance
interpretation of remote sensing data. Analogues of other planets' atmospheric dust, and dust in comets, asteroids, and circumstellar shells
