Malbunka Copper Mine, Alice Springs, Northern Territory, Australia

These Azurite “suns” from the Malbunka Copper Mine form in a fashion that is unlike any other Azurites that I've seen. These flattened discs of Azurite are formed between layers of Kaolinite which forces them to grow in a laterally compressed, radiating manner. The Azurite on this specimen has a beautiful blue color and an interesting texture.
