If a rock has shiny surfaces or bands of light and dark layers then it is?

The bands of light and dark are classic signs of Gneiss (Gneissose banding), but Gneiss is not necessarily shiny. It may be sparkly, but not shiny. However, a Slate IS shiny, but does not have the pretty banding. Another consideration is Schist, which has similar characteristics to Gneiss. My advise is that if you are classifying a rock that you are looking at, consider the grade of metamorphism, as it certainly is metamorphic. Also consider the mineralogy: what are the light and dark bands? Quartz, Feldspar (light)? Mica (biotite) (dark)? There are many possibilities. The mineralogy will help determine the original sedimentary rock, which you can then use to determine the metamorphic sample you have.


What is gniess luster?
