ANFO in contact with iron oxides can do what?

Explanation:
ANFO is a fuel–oxidizer mix (fuel oil with ammonium nitrate). When iron oxides are present, they can act as a surface that promotes rapid oxidation of the fuel oil, especially under heat or confinement. That makes the mixture burn very quickly – it can combust – rather than needing a booster to detonate or becoming inert. Combustion here means rapid oxidation producing heat, not an automatic, initiator-free detonation. So the best understanding is that contact with iron oxides can cause ANFO to combust.
