GEOLOGY

Detailed explanation-1: -Permineralization. The most common method of fossilization is permineralization. After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals, typically silica, into empty spaces, producing a fossil.

Detailed explanation-2: -Permineralization is a type of fossilization that happens when minerals transported by water fill in all the open spaces of an organism or organic tissue. Within these spaces, mineral deposits form internal casts.

Detailed explanation-3: -Permineralization occurs in porous tissue such as bone and wood. In this type of preservation, minerals dissolved in water such as quartz, calcite, or pyrite permeate the pore space and crystallize. The addition of these minerals results in denser and more durable fossils.

Detailed explanation-4: -A common form of fossilization is permineralization. This occurs when the pores of plant materials, bones, and shells are impregnated by mineral matter from the ground, lakes, or oceans. In some cases, the wood fibers and cellulose dissolve and are replaced minerals.

Detailed explanation-5: -Examples of permineralization Most dinosaur bones are permineralized. Petrified wood: Permineralization is the first step in petrification. In petrification, the cellulose cell walls are completely replaced by minerals.
