Description
Fossilized wood It is wood that has been transformed into stone through the process of permineralization. In this process, all organic matter is replaced by minerals, while much of the original structure – such as the rings of a tree – is preserved.
For this process to occur, special conditions are necessary: the wood must be buried in an environment that is poorly oxygenated (so that decomposition does not occur) and that has water currents rich in minerals.
The colors of fossilized wood are the result of the mineralization process – for example, the red and orange colors are a result of iron compounds, the green of copper, etc.
Some of the most famous areas where fossilized wood is mined is Ambilobe, Madagascar. The specimens there date back to the Triassic period, 220 million years ago, and most likely come from a conifer of the genus Araucaria.
