This happens to wood after minerals replace the wood fiber.?

When minerals replace the wood fiber in a process known as permineralization, the wood becomes fossilized and transforms into a substance called petrified wood. This process typically occurs over millions of years as groundwater rich in minerals permeates the wood, depositing minerals such as silica, calcite, or pyrite within the cellular structure. As a result, the original organic material is gradually replaced, preserving the wood's structure and appearance while turning it into a hard, stone-like material. Ultimately, petrified wood can display intricate details of the original wood, including growth rings and patterns, while gaining increased durability and resistance to decay.
