Sandwood

Sandwood is a type of wood that forms under specific geological conditions. It is not a distinct species of tree, but rather wood that has been fossilized and infused with sand or silicates over long periods. This process typically occurs when wood is buried rapidly in sandy environments, such as ancient riverbeds or coastal areas. The organic material of the wood is gradually replaced by mineral deposits from the surrounding sand.

The resulting material, sandwood, is often extremely hard and durable, sometimes exhibiting stone-like qualities. Its appearance can vary greatly depending on the original wood and the specific minerals present during fossilization. Colors can range from earthy browns and grays to more vibrant hues if colored minerals are involved. While often resembling petrified wood, sandwood specifically refers to the infill being primarily sand or silicate-rich sediments.

Due to its hardness and unique aesthetic, sandwood has occasionally been used for decorative purposes, such as in jewelry or artistic carvings. However, its rarity and the difficulty in working with such a dense material limit its widespread use. The term can sometimes be used informally to describe wood that has been heavily weathered and infused with sand particles, though this is a less formal and less permanent transformation than true fossilization.
