Oregon Petrified Wood

Petrified wood formed from ancient walnut, Myrtle wood, sycamore, and birch. The petrification process involves the gradual cellular replacement of decayed organic material by quartz crystals such as agate, jasper, amethyst, opal, or citrine. Ancient trees were washed into rivers or lakes, buried in sediments with the presence of volcanic ash in the anaerobic (oxygen-free) environment. The groundwater dissolved silica from the ash. The porous wood structure absorbed the silica-rich water, and, over time, the wood tissue was dissolved and replaced with minerals. This type of fossilization preserves the wood remarkably well allowing us to easily recognize fine details including growth rings, veins, and bark.
