![]() ![]() ![]() The best way of using petrified wood is to preserve the organic shape and natural curves and lines. Often petrified wood preserves the trace fossils of other animals such as insect borings and sometime even the scars of ancient forest fires. The beauty of any piece of petrified wood depends very largely upon the way it is polished as the polishing allows for the inner structures of the fossilized wood to be more easily seen. Reds/browns/yellows often come from iron oxides, pinks/oranges from manganese, greens from copper, etc. Petrified wood gets it’s often brilliant coloration from the different minerals that replace the organic material. Internal structures such as tree rings and wood grains can often be seen in petrified wood but evergreen trees do not exhibit cellular growth rings as they do not have growth seasons. Some pieces of petrified wood have retained the original cellular structure of the wood and the grain can easily be seen. Petrified wood is known for its exquisite color and detail. The source trees in Indonesian petrified wood is teak wood while the Arizona petrified wood is from coniferous trees. There are many reasons why petrified wood from different areas of the world looks different depending on the nature of the source trees, the age of the wood-stone and the nature of the surrounding material or matrix rock. Petrified wood has been found in many locations including Oregon, Nevada, Arizona, Washington and Madagascar, Indonesia, Bolivia, Egypt, Canada. If they are found to be valuable, they are sold to companies who clean, cut and generally process the piece into polished petrified wood. Experts are then called in to examine the piece to determine if it is worth excavating. When a farmer is plowing his land, he can sometimes unearth a piece of petrified wood. Petrified wood in Indonesia is often hidden deep under ground. ![]() Well known petrified forest are located on the island of Lesbos, in Greece, and in Arizona, USA. ![]() It is strictly forbidden to remove petrified wood from these locations. There are known "petrified forests", where tourists can explore. In most countries the pieces are small and the coloration tends to be bland. Top quality pieces are to be found in Indonesia, USA, Madagascar and Brazil. In some countries, petrified wood can be found in large quantities, made up of large pieces which are brightly coloured. Petrified wood can be found all over the world in many locations including Oregon, Nevada, Arizona, Washington and Madagascar, Egypt, Bolivia, Canada, Indonesia. Minor minerals, such as iron, manganese, and carbon add the rainbow of colors. The mineral silica, from volcanic ash, in various stages of crystallization replaced most of the organic wood. This petrification process generally results in a quartz chalcedony mineralization. Structures such as tree rings and the various tissues are often observed features. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing mineral laden water.The result is a fossilized plant of the original woody material that often exhibits preserved details of the bark, wood, and cellular structures. This process is slow and lasts for milleniums during which the organic remains is replaced by minerals and then replaced with stone. Then, groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silica, calcite, pyrite, or other inorganic material such as opal in a process called permineralization. Millions of years ago prehistoric trees were rapidly buried by sediment and protected from decay. ![]()
