Where does petrified wood come from?

Petrified wood (from the Greek petro meaning "stone", literally "wood turned to stone") is a fossil. The process of petrification occurs when wood is buried under a layer of sediment where it is first preserved due to a lack of oxygen. Mineral-rich water circulates through the sediment and gradually replaces the wood cells with minerals. Less than a hundred years would be necessary for some pieces of wood to be petrified. Petrified trees are found primarily in Arizona, Madagascar and Indonesia. The history of petrified trees begins 225 million years ago in a huge forest consisting mainly of araucarias, schilderias, ginko biloba and woodworthia. Petrified wood can be found all over the world, and sometimes in exceptional forms, because of the species or the size. For example, in Argentina, there is a park in Patagonia that has petrified trees of more than 3 meters in diameter and 30 meters long. In Australia, there are petrified and opalized woods. In the United States, there is the gilboa forest which is the oldest known petrified wood forest (more than 380 million years). The main deposits: Argentina, Australia, Brazil, Russia, United States, Canada. Two cataclysms are at the origin of this phenomenon which gave birth to petrified wood. The first one: a gigantic flood is going to tear off thousands of trees of this forest. They will be dragged on 300 kilometers and will finish their race in lagoons or river plains. Immersed, thus protected from the air (anaerobic environment), the trees will not rot. The second cataclysm: a volcanic eruption that will project an incredible quantity of ash, covering the trees with a mantle up to 800 meters thick. The ash was dissolved in water and mixed with other sediments. This "soup" rich in mineral components will slowly penetrate inside the trunks. It is no longer wood but a mineral. Fossil trees do not contain wood anymore but are made of hydrated micro crystalline quartz. These minerals, which settle and replace the wood, reproduce the patterns of the wood structure. The wood is constituted of more or less soft material and that the substitution of the wood by the mineral is done more or less quickly according to this hardness of the initial material). During the process of petrification certain cavities were filled with agate, amethyst or citrine. It is about a pseudomorphosis.
