Petrified Wood

Petrified wood is a type of fossilized wood that forms when plant material is buried under sediment and mineral-rich water flows through it over millions of years. During this process, the organic material is replaced with minerals like quartz, calcite, or pyrite, while retaining the original structure and texture of the wood.

Key Features:

Appearance: Often resembles wood but is stone-like, with colors ranging from brown and red to yellow and green, depending on the minerals present.

Formation: Typically occurs in volcanic or sedimentary environments where silica-rich water is abundant.

Preservation: Preserves fine details like growth rings and bark texture.
