In geology, banded metamorphic rock containing eye-shaped mineral patterns; from German 'auge' meaning 'eye.'
From German 'augengneiss,' literally 'eye-gneiss.' The eye-shaped patterns form during metamorphic processes when minerals arrange into distinctive shapes.
When rocks are subjected to incredible heat and pressure deep underground, minerals reorganize into beautiful patterns—augen gneiss looks like it's watching you!
