You might be surprised! Experimental wood fragments were silicified to nearly 40% by weight over a period of 7 years by the deposition of amorphous silica spheres in cell lumina of wood tissue.”, They go on to say that the results of this study confirm that under the perfect conditions, silicified wood can form “…in time periods as short as tens to hundreds of years.”.

This petrification process generally results in a quartz chalcedony mineralization. Elements such as manganese, iron, and copper in the water/mud during the petrification process give petrified wood a variety of color ranges.  The organic materials making up cell walls have been replicated with minerals (mostly a silicate, such as opal, chalcedony, or quartz). The good news is that you can legally take any petrified wood you find on property that you personally own. Petrified Wood Today.

Rivers flooded by tropical rain storms washed mud and other sediments into the lowlands. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red, or another tint. Mineral-laden water flowing through the sediments may lead to permineralization, which occurs when minerals precipitate out of solution filling the interiors of cells and other empty spaces. In the right conditions, wooden logs buried underground for millions of years slowly transform into petrified wood.

So, petrified wood is over millions of years old. Due to this information is subject to change at any time, the Oregon Discovery team cannot guarantee that is either current or correct. Most of the petrified wood in Washington grew during the Miocene Epoch, some 5 -12 million years ago, when the state was swampy and mild, and played host to vast forests of cypress, oak, elm, and ginkgo trees.
