Middlebackite (Australia)
An organic mineral discovered in the Iron
Monarch quarry, in the Middleback Ridge,
Australia. Photographer Peter Elliott.
Marklite (Germany)
This mineral is very similar in composition to
malachite and azurite. It’s named after Dr.
Gregor Markl who found the specimen.

range during formation that is only found in
the Plavno mine. Photographer Travis Olds.
