Metamorphic
Same old ingredients made into a different cake. Slow heat and pressure rearranges almost any kind of rock into foliated minerals (gneiss) or layers (migmatite). Mother Nature's putty. Polished panel at the entrance to the Vale Gallery, Museum of Nature, Ottawa, Canada.
Pls see my Geology ABCs gallery for more about what rocks have to tell us, as shared by flickrites near and far.
