Metamorphic Rock Identification I

If the minerals in a rock seem to be layered into dark and light bands, and the bands are somewhat folded or faulted, it´s a metamorphic rock (gneiss). If the rock doesn´t have layers, and if the crystals in it all seem to be shiny and flat (mica) then it´s probably a metamorphic rock (schist, phyllite). If the rock isn´t 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, it´s probably shale, which is sedimentary, not metamorphic.)
