AZURITIC
BRECCIA
Rocks containing the copper hydroxy-carbonate minerals
azurite and malachite are often quite attractive specimens.
Below is a breccia that has extensive azurite mineralization (blue - Cu3(CO3)2(OH)2)
with some minor malachite mineralization as well (green - Cu2CO3(OH)2).
This azuritic breccia comes from the 5100Õ level of the Phelps Dodge Morenci
Mine, an open-pit mine on the west side of Chase Creek, north of the town of
Morenci in western Greenlee County, southeastern Arizona, USA (33¡ 05Õ 26Ó
North, 109¡ 21Õ 58Ó West).
