About petrified wood (from the page): "Petrified wood is a type of fossil: it consists of fossil wood where all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant’s cells and as the plant’s lignin and cellulose decay away, a stone mould forms in its place."

Amazing colors and textures! Great finding.

My parents have some petrified wood. It really is neat.

Learn something new here at clipmarks everyday. Who knew? I thought wood was brown. :~)

Very interesting clip!
