| 1 | 00.4.23.699.7 | Petrified Wood | The term petrified comes from the Greek root “petro”, meaning “rock”. A million-year process involving mineral-rich water and a removal of oxygen creates an internal mold of the tree. The minerals in the water at the time of fossilization are evident by color, even after millions of years. Copper, cobalt, and chromium show as green and blue hues; iron oxides exhibit reds, browns, and yellows; and carbon and manganese oxides leave hints of black, as seen in this example. Petrified wood can be found all over the world, this Giant Redwood came from California where there is a Petrified Forest. |
