Video of schist. Look at the surface as it moves, you will see it catch the light. Does this help you work out what minerals may be present?
3D model of a gneiss.
Gniess gigapixel images. Click to open and click red circles to view magnified images. This is a different gneiss from the 3D model but shares similar characteristics.
