Petrology was one of my favorite classes, but I really only took the one. Well, plus field geo which includes a lot of that. I was a soft rock geologist *runs and hides*

You guys have some rockin' (yes, pun intended) geology over there. Passive margin=boooring (well, mostly. Unless you think about the methane hydrates off the East Coast here and think about what would happen if they slumped. Funtimes!)
