Geosonnet 68

A hickory, a dickory, a dock
Diffusion rate of mice when timing’s known
But atoms, unlike rodents, have a clock
Which contradicts the others, all alone.

“A thousand Years,” says fat man Barium.
M-g squeaks, “Nah mate, more like less than one.”
T-i says, “Where’s my honorarium?
I can’t work here, diffusion’s not begun.”
He’s right! The two plus profiles haven’t moved.
The curves are melt dilution marks instead
The timescale’s not millennia, it’s proved
It’s more like months, and barium misled.
   Basalt melts felsic crystal mush so fast
   A season’s all you get before the blast.
