Why Are Only A Few Fossils Found In Marble

Recrystallization obscures the original fossils and sedimentary structures of the limestone.

Why are only a few fossils found in marble.

Fossil in marble fossil in marble experiment level elementary introduction. These are bones shells and marks in the stones. The heat and pressure required to change or metamorphose rocks usually destroys any fossils. The criteria of fossil dating is based on biostratigraphy i e.

The order the successions of sedimentary rocks based on their paleontological content. It also occurs without forming foliation which normally is found in rocks that are altered by the directed pressure of a convergent plate boundary. In its pure form marble is a white stone with a crystalline and sugary appearance consisting of calcium carbonate caco 3 usually marble contains other minerals including quartz graphite pyrite and iron oxides these minerals can give marble a pink brown gray green or variegated coloration. Big animals and plants fossils are very difficult to find out.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. 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. However special circumstances do happen. Recrystallization is what marks the separation between limestone and marble.

Fossils rarely occur in metamorphic or igneous rocks. Fossils are some living things remains which lived long time ago and are extinct now.
