Native copper infiltrating woodWe recently shared (see http://on.fb.me/1Ot7Ms1) a piece of mine timber from an old copper mine in Arizona that was partially replaced by the copper carbonate azurite, precipitated from the waters percolating through the metal rich mine. In this sample, from the antique copper mines of Troodos in Cyprus that fuelled the Bronze Age around the Mediterranean (see http://on.fb.me/1Oleeph), a slice of trunk has been infiltrated by copper rich waters, and the pure native metal has precipitated within its grain, each zone surrounded by a faint green area tinged with copper oxides.
