Copper Petrified Wood. The tag that came with sample reads as follows: Petrified wood from the Nacimiento MineBut it's the copper we're interested in here! The green color indicates that copper is a major constituent of whichever minerals make up this sample. In fact, I traded this sample for a few of my strange copper nodules.
