Huge Copper Log 

Yes. Almost entirely replaced by Chalcocite, which is Cu2S. More in the description above. The plant matter is around 260 million years old. It lived and died on the continent of Pangea, some 6,000 miles of continental drift away from where we dug it up in New Mexico. It is very dense. Quite a workout to move any, let alone one this size. I don't generally take naps, but I took one after we got that sucker back to the rig.

@@lostadamsgold that's freaking amazing. Priceless indeed
