Pegmatite is a intrusive igneous rock, which means it's formed through cooling and consolidation of magma, below the surface of the earth. This rock is mostly found in the major cratons (old and stable parts of the continental lithosphere). Their importance results by the fact that they often contain rare minerals such as aquamarine, topaz or fluorite.
Another rock that astonishes with the texture and the farrago of colours. I really love the pink particles...Everyone needs a feminine touch...even a hard rock...
I can't decide if it looks more as the spume made by soap or as the skin of a reptile. I think I will stick with the second opinion. What do you think?
The most broadcast rock from the Earth's crust. It comes in different combination of colours, each of them representing another mineral.
