Petrified Wood Polished Stone Slab Henry Mountain Utah
This is a gorgeous polished Petrified Wood piece that has been sliced and polished on one face.
The Petrified Wood stone slab is 6 inches and by 3.9 inches wide and about 1/4 to 1/2 thick.
It has natural rough, or bark, on the edges but is not quite a perfect full round as the both sides have some slight damage.
It is Petrified Wood from Utah, in the Henry Mountains area.
The Henry Mountains are a group of peaks formed by volcanic activity and uplift. Located in south-central Utah, just north of Lake Powell, and to the east of the Grand Staircase-Escalante National Monument, the Henry Mountains and surrounding deserts make up almost two million acres of public land.
It is part of the Morrison Formation, a sedimentary rock formation that dates to the Late Jurassic Period (approximately 155 to 150 million years ago).
Most of what is found in this rich deposit is Araucaria (conifer).
This petrified wood piece is from the Kirkby collection and was self-collected sometime in the 1930's to the 1960's.
Petrified Wood formed when a tree died and was quickly buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
