Happy Valentine’s Day, everyone! For those of you who are grumpy on Valentine’s Day, here’s a heart of stone. For the geologists, this heart of stone that should make you slightly less grumpy. There are some good stones in there, including gabbros, purple calcite, nummulite-bearing rock, and some excellent shell fossils.

I’ve had a busy Valentine’s Day. I’m tired from spending 12 hours working on my thesis, but at least it was a good, productive day. My husband is away at sea, so at least I’m not missing a romantic evening. Although my two cats are seeking cuddles at the moment, so perhaps I’ll make them my valentines.
