1
Tip of the Week
If the minerals in a rock seem to be layered into dark and light bands, and the bands are somewhat folded or faulted, itīs a metamorphic rock (gneiss).
If the rock doesnīt have layers, and if the crystals in it all seem to be shiny and flat (mica) then itīs probably a metamorphic rock (schist, phyllite).
If the rock isnīt very shiny, is mostly one color (for example, dark gray) and breaks into very hard, flat sheets it is probably a metamorphic rock (slate). (If the sheets are flat and crumbly, a soft rock, itīs probably shale, which is sedimentary, not metamorphic.)
