The water is exuberant of silicon dioxide that it change state from volcanic ash. As the silica water fills up the cells of the logs it crystallizes into mineral quarts or opal (Trees to Stone, p.2).

Making the logs level more beautiful, put beneficial rich mineral deposits seeped into the logs during the fossilisation process and a rainbow of colors became a permanent chef-doeuvre for us to see. This process fossilizes the log in such an study way that the surface of the log is exactly as it was millions of days ago. One might ask, if these logs were buried about 250 million years ago, how are we able to see them at one time? Well, thousands of the logs are probably still buried, but some of the logs were brought... If you assume to get a full essay, order it on our website: Ordercustompaper.com
