Environmental geochemistry of ancient volcanic ashes [PDF]
Journal of Hazardous Materials, 2010 Volcanic ashes from the Puna and surrounding Andean areas in northern Argentina show that sometimes volcanic ash deposits are very well preserved (up to several million years) and can remain a potential hazard for the environment in a similar way as current deposits.

Volcanic ash classification through Machine Learning
Geochemistry, Geophysics, Geosystems, 2023 Volcanic ash provides information that can help understanding the evolution of volcanic activity during the early stages of a crisis, and possible transitions towards different eruptive styles. Ash consists of particles from a range of origins in the volcanic system and its analysis can be indicative of the processes driving activity.
