Why Are Only A Few Fossils Found In Marble

However special circumstances do happen.

Why are only a few fossils found in marble.

Traces of fossils are sometimes found in metamorphic rocks deriving from metamorphic processes of low intensity on sedimentary rocks. Big animals and plants fossils are very difficult to find out. Fossils are some living things remains which lived long time ago and are extinct now. These are bones shells and marks in the stones.

But small fossil fusulina is easy to see in the marble around you. It also occurs without forming foliation which normally is found in rocks that are altered by the directed pressure of a convergent plate boundary. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. The criteria of fossil dating is based on biostratigraphy i e.

The order the successions of sedimentary rocks based on their paleontological content. Fossils rarely occur in metamorphic or igneous rocks. 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 heat and pressure required to change or metamorphose rocks usually destroys any fossils.

Fossil in marble fossil in marble experiment level elementary introduction. For example fossilized shells and bacteria have been found in marble which is metamorphosed limestone.
