As we know from Laura’s work, the likelihood is a cometary intrusion into the story.
Hello,
I had a look in the chemical markers and here is what it shows for the 430 BC period:
From what I've read, a potential match with a comet is when those four markers are present together (ammonium, sulfate, chloride, nitrate):
It was then observed that there is a large concentration of ammonium in the American GISP2 ice core at the time of the Tunguska impact.
... there were also high levels of chlorine, nitrate (nitric acid) and sulphate (sulphuric acid) in exactly the same layers of ice
The first chart shows four spikes, and the other charts show five spikes, the additional being around -401. Could it be a volcano?
The above dates may not be extra accurate, so just for the illustration!
