GEOLOGY

Detailed explanation-1: -Permineralisation occurs when dissolved minerals carried by ground water fill up space inside the cells of plants and animals. The dissolved minerals crystalise in these cellular spaces and eventually form rocks in the shape of the animal or plant.

Detailed explanation-2: -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-3: -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-4: -Amber fossils are made when insects or other very small animals become trapped in thick tree sap. The sap hardens over time to become amber, and the body of the animal is preserved intact. Large animals such as humans cannot become stuck in tree sap, so they do not form amber fossils.

Detailed explanation-5: -Sometimes when an animal dies and its body decays, it can leave an imprint in the sediment. If this imprint fills in with minerals from sediment and groundwater, it can harden to form a fossil. This fossil is called a cast fossil. The fossilized imprint is called a mold fossil.
