Petrified wood is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree having turned completely into 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 wood.

Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. Mineral-laden water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay, a stone mould forms in its place.

In general, wood takes less than 100 years to petrify. The organic matter needs to become petrified before it decomposes completely. A forest where the wood has petrified becomes known as a Petrified Forest.

Elements such as manganese, iron and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red, or other tint.


Origin Of The Name

Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone")

It is the result of a tree having turned completely into stone by the process of per mineralization. All the organic materials have been replaced with minerals (mostly a silicate, such as quartz), while retaining the original structure of the wood. In general, wood takes less than 100 years to petrify. The organic matter needs to become petrified before it decomposes completely.

Native Americans had various beliefs about the origin of the petrified logs in what is now Petrified Forest National Park in Arizona. Natives of the Paiute tribe held that these giant petrifications were spent arrow shafts and spears dispatched by the Thunder God Shinauav and his enemies during a great battle. Members of the Navajo tribe believed they were the bones of the great giant monster Yeitso.



Where Is It Found

Petrified wood is found all over the world. Places such as USA, United Kingdom, Ukraine, New Zealand, Namibia , Libya, Indonesia, India, Greece, Egypt, Ecuador, Germany, Czech Republic, China, Canada, Brazil, Belgium, Australia & Argentina.



What Do We Do With It

Petrified wood is used to make a wide array of decrorative items from lamps and tabletops to dishes and jewelry. The petrified wood forest of the United States are now protected by law and only limited amounts are now permitted to be collected.



Metaphysical Uses

Petrified wood:  connection to earth and nature; removes petty annoyances. Works with the root chakra. Petrified wood is a stone that is good for grounding and stabilizing one's emotions. It is particularly useful in calming svival-based fears. It helps one be practical. It is a stone of business success. Petrified wood is a good stone for general protection. Physically, it is beneficial physically for the bones, backaches, skin and hair. Petrified wood is also used for past life regressions because of its inherent link with the past.
