Petrified wood is the name given to ancient wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, primarily silica leaving much of the detail such as tree rings still visible. For this to happen the wood needs to be buried in an environment both low in ...
Sale ends soon. Shop Petrified Wood Sculpture Large. Petrified wood is a magical natural material that occurs when a tree dies and silicon dioxide forms in place of the degrading wood. After thousands of years, there is no wood left—only quartz.
Petrified wood is a type of fossil that started out as a tree but now more closely resembles a stone. That’s because it that has undergone permineralization, a process that occurs when minerals gradually fill in the tree’s cavities. The value of petrified wood depends on the size, color, and quality of the piece, slab or log.

Large petrified tree trunk Pieces of petrified wood next to a Welwitschia in Namibia The Petrified forest, located west of the Namibian town of Khorixas, on the C39 road, is a deposit of large tree trunks that have "turned to stone" through a process of diagenesis. There are at least two large tree trunks, each long, exposed to view. Several hundred others are located in the vicinity. It is believed that the trees were swept downstream by a large flood and covered by alluvial sands. Deprived of air, the organic matter could not rot and decay, but instead, over millions of years, underwent silicification, whereby each cell is individually fossilised and the appearance, if not the colour, of wood is retained. The surrounding sands became sandstone, which is now eroding away. In addition, there are a large number of welwitschia plants at the site. The site was declared a National Monument on 1 March 1950.
Escalante Petrified Forest State Park (also known as Escalante State Park) is a state park of Utah, USA, located a half-mile (0.8 km) north of the town of Escalante. A visitor center was built in 1991, and features displays of plant and marine fossils, petrified wood and fossilized dinosaur bones over 150 million years old (Upper Jurassic Period). The Petrified Forest Trail is a one-mile (1.6 km) loop, winding up the side of a mesa to the top where most of the fossil wood occurs. Logs two feet or more in diameter are seen at several places along the trail where it is eroding from the conglomerate capping the mesa. This conglomerate lies near the top of the Brushy Basin Member of the Morrison Formation. The wood is multicolored (mostly red, yellow, white, and black) and was prized by hobbyists before the Park was established. The logs are believed to be of conifers that were transported by a river before being buried and later fossilized as agate. A 50 foot (15m) log is displayed near the trail head and is one of the most complete fossil logs known from the Morrison Formation. Fossil log displayed at Escalante Petrified Forest State Park, Utah. This 50 foot (15 m) log is one of the longest known from the Morrison Formation The Sleeping Rainbows trail is an optional loop off the Petrified Forest Trail. This section is much steeper and requires scrambling and climbing over rocks. In 1954 Wide Hollow Reservoir was constructed to provide irrigation for the town of Escalante. The reservoir is stocked with rainbow trout and bluegill, and is popular for water sports including swimming, boating and fishing.

It is the result of a tree or tree-like plants having completely transitioned to stone by the process of permineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the stem tissue. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three-dimensional representation of the original organic material.
