Expedition 04: Rostende Steine

Rostiger Gneis.

Description

Did you also notice the reddish stones in the glacier forefield? Take one in your hand and take a closer look: below the surface you can see that it is the same gneiss as the one that occurs everywhere here. But rust has formed on the stone in your hand. The black mica in gneiss contains iron, which can oxidize upon contact with oxygen and moisture, i.e. rust. The higher the humidity and temperature, the faster the rust formation.

Do you want to know more about gneiss? Then listen to the audio. The audio file can be found at the back of the pictures. 

Directions
Follow the marked hiking trail.
