A cluster of Azurite rosettes with some Malachite in a matrix of limonite from
the Morenci Mine in Arizona.
A broken mass of botryoidal Azurite showing its concentric growth pattern from
the Morenci Mine, Arizona.
An Azurite
rose of intergrown crystals from Utah.
This specimen shows the typical association of Azurite with Malachite in
Limonite. It is from the oxidized zone of a chalcopyrite vein (primary
sulfide) of an ore body in the Morenci Mine of Arizona.
Concentric layers (botryoidal mass) of Azurite and Malachite.
Azurite with minor amounts of Malachite on Limonite from Morenci, AZ.
