This timescale is currently unconstrained - measuring the lifetime of ferrocyanide salts will be crucial to constrain their role in the early stages of prebiotic chemistry! (3/3)

constraints on Earths’s early bombardment.

Double impact scenarios are therefore extremely unlikely settings for the initial stages of prebiotic chemistry, unless ferrocyanide salts are stable on 1000yr timescales in crater environments. (2/3)

The plausibility of origins scenarios requiring two impactors Hydrogen cyanide delivered by cometary impactors can be concentrated as ferrocyanide salts, which may support the initial stages of prebiotic chemistry on the early Earth. One way to achieve the condi...

The impact shock heating of ferrocyanide salts is one potential way to support several prebiotic scenarios, requiring both cyanamide and cyanoacetylene. We show however that an initial cometary impact is extremely unlikely, given available (1/3)
