How is petrified wood created?
Petrified wood, or fossil wood, is a stone that is formed from trees that have ended up under thick layers of volcanic ash. The ash contains all kinds of minerals, which slowly dissolve in the groundwater. Because the trees are no longer in contact with oxygen, the wood does not rot as quickly as normal. In the meantime, the groundwater soaks the tree with minerals where they are deposited in the wood cells. Slowly but surely the wood decays and the minerals take the place of the wood cells. This goes very slowly, so that the structure of the wood is perfectly preserved in the minerals.
220 million years old
Petrified wood therefore no longer contains real wood, but only the imprint of the tree formed by minerals. These pieces from Madagascar are 220 million years old and are filled with richly colored minerals.
Petrified wood is the stone of wisdom, it imparts psychic abilities and gives you a sense of security when you feel disconnected from the world
