Petrification.
Cardboard is made primarily of cellulose fibers derived from wood pulp, so it does not contain minerals in significant amounts. However, small traces of minerals like calcium, magnesium, and potassium may be present from the manufacturing process or from any additives used in the cardboard production.
permineralized fossil
No, wood does not contain rocks. Wood is a natural material that comes from trees, while rocks are made up of minerals and are typically found beneath the Earth's surface.
Petrified wood is considered a rock, one that may be composed of a single replacing mineral, often quartz or pyrite, but possibly with others in combinations. Petrified wood is not considered metamorphic. It is also considered a fossil.
Crystals
Everything has fibers. Even wood. So wood does have something to do w/ fibers
Wood fibers can be obtained from wood by various mechanical or chemical methods. In mechanical pulping, wood chips are mechanically broken down into fibers. In chemical pulping, wood chips are cooked in chemicals to dissolve lignin and separate fibers. These fibers can then be used to make products like paper, textiles, and composite materials.
it breaks down the cellulose in the wood and plant fibers; it eats the wood and plant fibers
Lignin is the material in wood that holds it's fibers together.
tree fibers of wood
The size, direction, arrangement, appearance, and quality of wood fibers are known as wood grain. It refers to the texture and pattern of wood fibers visible on the surface of a cut piece of wood, which can greatly impact the aesthetics and characteristics of the wood.
Pulp is softened wood fibers used to make paper.
The description fits that of a petrified tree, which used to live in the southwestern US before being replaced by minerals that preserved its structure and turned it into stone.
The direction that fibers run in wood is called the grain. Grain direction is important in woodworking as it affects the strength, stability, and appearance of the wood.
Cardboard is made primarily of cellulose fibers derived from wood pulp, so it does not contain minerals in significant amounts.
