Why Are Only A Few Fossils Found In Marble

The heat and pressure required to change or metamorphose rocks usually destroys any fossils.

Why are only a few fossils found in marble.

Fossils are some living things remains which lived long time ago and are extinct now. For example fossilized shells and bacteria have been found in marble which is metamorphosed limestone. Fossils are inherently delicate things and therefore precious little would withstand the conditions that are required to create marble and therefore marble hardly ever contains fossils as a. The order the successions of sedimentary rocks based on their paleontological content.

Traces of fossils are sometimes found in metamorphic rocks deriving from metamorphic processes of low intensity on sedimentary rocks. Fossil in marble fossil in marble experiment level elementary introduction. But small fossil fusulina is easy to see in the marble around you. However special circumstances do happen.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. Fossils rarely occur in metamorphic or igneous rocks. Big animals and plants fossils are very difficult to find out. It also occurs without forming foliation which normally is found in rocks that are altered by the directed pressure of a convergent plate boundary.

Recrystallization is what marks the separation between limestone and marble. The criteria of fossil dating is based on biostratigraphy i e.
