4" Gary Green Jasper (Larsonite) Bog Wood Stand Up - Oregon
This is a 4" tall section of jasper replaced petrified wood that was collected near McDermitt, Oregon. This section has been polished to a glossy finish on one side and the base has been cut flat for aesthetic presentation. The red coloration of this specimen is likely a result of cinnabar impurities.
Gary Green Jasper, also referred to as "petrified bog wood" and/or "Larsonite" is a form of petrified wood from a location near McDermitt Oregon, on the Nevada/Oregon border. It's believed to be wood that was covered by volcanic activity between 11-15 million years ago. The volcanic event covered this area in debris that deprived the plants of oxygen, halting the decay process. Minerals from the volcanic ash then acted as the replacement material for this petrification/mineralization, giving the wood these vibrant colors.
