Petrified Wood Slices - Size #4
This is a hand-polished Petrified Wood Slice. The coloring of this crystal is wonderful, with a beautiful bandage, multidimensional shade, surrounded by a petrified bark, some pieces show growth rings and structure throughout. Most pieces have a polished face and a rough face while few are polished on both sides.
Petrified wood is the name given to a special type of fossilized remains of vegetation. Petrifaction is the result of a tree or tree-like plants having been replaced by stone.
The name given to timber converted into stone (fossilized) is petrified wood by the technique of permineralization. In order to do this, the wood must be buried in a low-oxygen setting and with flowing, mineral-charged water. Organically important materials, such as tree rings, have their natural formations in place.
Some specimens of petrified wood are such accurate preservations that people do not realize they are fossils until they pick them up and are shocked by their weight. These specimens with near-perfect preservation are unusual; however, specimens that exhibit clearly recognizable bark and woody structures are very common.
The most famous location of petrified wood is in northeastern Arizona in the “Petrified Forest National Park” where around 225 million years ago the area had a tropical climate and was covered in a dense forest. the rivers flooded which caused mud and other sediments into the land which caused the trees in the area to die. enormous 9ft trees in diameter that were 200ft tall had fallen, over time volcanoes in the area had erupted causing the area to be covered in high silica content, the dissolved ash served as the substance to transform the trees into its petrified state.
