Ochtendung is situated in the Vulkan Eiffel. Also for this location I was inspired by the great photos of Fred Kruijen, that were published in the Dutch Gea Magazine. The most interesting minerals can be found in xenolites, material that is not originating form the lava but from deeper layers. That is, if you can find them. I was not very succesful though. So for now the pictures shown are a bit more average Vulkan material.
