Although not much is known about how or why a tree becomes petrified, it is now thought that it takes place through a process known as infiltration. As the sediment water, rich in minerals, seeped into the wood, it deposited the minerals in the air spaces within the wood tissues until all of the microscopic spaces in the wood were filled. It is theorized that the original wood acted as a framework to hold the minerals as they solidified, and the logs literally became stone with only 2% of their volume taken up by wood cellulose fiber.
The mineral deposited in the wood was silica in all its various forms. Petrified Wood logs of almost pure silica are white or light tan or gray. But impurities in the silica, such as iron oxide, stain the trunks yellow, orange, rust and red while manganese oxide creates blue, black or purple colors.
