If so, have you ever howled at silly mineralogical mistakes in a piece of fiction? Wanna prevent me from making you scream?
I’m in the midst of worldbuilding, you see, and I’ve just come across the uncomfortable fact that I know bugger-all about minerals. I know some basics: that when a geologist is talking about a mineral, it’s not the same type of mineral your nutritionist will be yammering about. I know rocks are made of minerals, and that some minerals are commercially useful. I can, if pressed, name a few. Well, probably several. And that’s about it.
It’s pathetic is what it is.
