Pegmatite

Transcript:

Sarah: Awesome. So we're gonna head a little bit further down. This is another ROM-only rock. This is -- we're gonna go find our pegmatite, which is actually, I think, my one of my favorite ones that we've created. So let's go down into the volcano, down deep where it's very, very hot. And here is our pegmatite. 

Kim: I am thrilled that you've added pegmatite to your Minecraft world. It is such a cool rock. It is an intrusive igneous rock, so it means that it likes to crystallize in the Earth, it doesn't extrude onto the surface, it sits inside, and what's really interesting about pegmatites is they take a long, long time to crystallize, so they form these really big crystals, sometimes the size of cars, sometimes the size of houses. They just grow, and grow, and grow. 

And what's also really cool about pegmatites, if you think of all these volcanic rocks as sort of like soup, okay? So you, in your normal soup, you like to take the the ingredients that form soup, so, like, chicken noodle soup, they'll take the noodles, it'll take the carrots, they'll take the celery, but it's not gonna take the black licorice, it's not gonna take all of the candy corn, those things don't go into soup, right? So what's cool about pegmatites is that they take all of the elements that don't like to be in other types of rocks and they form really interesting minerals. All the leftover stuff gets all mixed together after all the more common or compatible elements go somewhere else. These are the incompatible elements, and that's where you find the really cool and interesting new minerals.
