How is copper carbonate formed in nature

  1. i read on wikipedia that
    2 Cu (s) + H2O (g) + CO2 + O2 → Cu(OH)2 + CuCO3 (s)

    although doesnt the copper form copper oxide first? and then the copper oxide reacts with water and CO2 to form copper carbonate and copper hydroxide?

    Wikipedia gives just the overall reaction equation. No idea about exact mechanism, although I would be surprised if it would be not researched to death. Sorry, I have no access to literature so I can't check it.
