Hello list,
Ordinary chondrites generally contain around 2% troilite (iron sulfide,
FeS); the thin section made of the Carancas meteorite shows even more,
around 5%. Troilite dissociates at high temperatures (e.g. a hypersonic
impact), releasing hot sulfur vapor, which in turn will oxidize in

Thanks for the reactions both public and private to my posting to the list
about sulfur dioxide at Carancas. This thread has also given me a new idea
about the boiling water in the crater. Yes, it may have been the obvious:

Ground penetrating radar (GPR) is commonly used for non-destructive
investigation of archaeological sites. GPR can detect objects, changes in
