Why Are Only A Few Fossils Found In Marble

However special circumstances do happen.

Why are only a few fossils found in marble.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. For example fossilized shells and bacteria have been found in marble which is metamorphosed limestone. 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. Recrystallization is what marks the separation between limestone and marble.

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. 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.

Recrystallization obscures the original fossils and sedimentary structures of the limestone. But small fossil fusulina is easy to see in the marble around you. Fossils rarely occur in metamorphic or igneous rocks. Big animals and plants fossils are very difficult to find out.

These are bones shells and marks in the stones. The heat and pressure required to change or metamorphose rocks usually destroys any fossils.
