Okay, here’s what I’ve got so far (some are common around the internet, others are things we’ve come up with in our geo department):
Geology is the schist
Rocks are really gneiss
Do we have an apatite for geology? You breccia!
All my faults are stress related
Igneous is bliss
That’s some perfect cleavage
My sediments exactly
We don’t take geology for granite
Geologists are a little bit wacke
It’s been a tuff day
May the quartz be with you
Pyrites of the Caribbean
Let’s try and start with a clean slate
I realized I was getting old when a geologist dated me
Meteorites and meteor-wrongs
If you like geology you stalagmite be stalactite
My feelings toward geology are purely plutonic
