The azurite was formed by ground water carrying copper ions moving though the bedding planes in the kaolinite rock formation. Carbonate and copper in the groundwater has nucleated around quartz grains in the kaolinite. The chemical reactions resulting in crystallizing of the azurite have taken place along preferred bedding planes and have moved out evenly from the point of nucleation, often producing near perfect circles.
