Petrified Wood

What is Petrified Wood?

Petrified wood is formed when a tree or branch is submerged in mineral rich sediment for millenia This most probably occurs as a result of a natural disaster, for example where volcanic ash or a mudslide covers a forest. The wood is initially preserved due to the lack of oxygen in an anaerobic environment. Over the course of millions of years the organic parts of the wood; the cellulose and lignin in the trees cells are gradually replaced by the mineral deposits flowing through the sediment or mud. The petrified wood retains its original form and in many cases the trees growth rings can be clearly seen, at a microscopic level even cells can be observed.
