Hi Sterling, Eric, all,

I'd be careful with those Sr numbers, as it appears
from the C14 and Be10 production that neutrons and
protons may be released in hypervelocity impacts.
  
Based on the impact products of recent large iron
impacts and cometary impacts, I am tending to think
that the impactor may provide much of the material for
tectites.

Of course, if the NASA budget was not controlled by
Mars nuts, we might have some answers to those
important questions by now.
