Why are only a few fossils found in marble.

Big animals and plants fossils are very difficult to find out. 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. For example fossilized shells and bacteria have been found in marble which is metamorphosed limestone. 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. Recrystallization obscures the original fossils and sedimentary structures of the limestone. These are bones shells and marks in the stones. Fossils rarely occur in metamorphic or igneous rocks.

The heat and pressure required to change or metamorphose rocks usually destroys any fossils. Recrystallization is what marks the separation between limestone and marble. Fossils are some living things remains which lived long time ago and are extinct now. Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat.

But small fossil fusulina is easy to see in the marble around you. Traces of fossils are sometimes found in metamorphic rocks deriving from metamorphic processes of low intensity on sedimentary rocks.
