Will you find fossils in metamorphic rocks?
Will you find fossils in metamorphic rocks?
Metamorphic rock, such as marble, is formed by tremendous heat and pressure. Fossils are not usually found in either igneous or metamorphic rocks.
Are fossils found in sedimentary rock or metamorphic rock?
sedimentary rock
There are three main types of rock: igneous rock, metamorphic rock, and sedimentary rock. Almost all fossils are preserved in sedimentary rock. Organisms that live in topographically low places (such as lakes or ocean basins) have the best chance of being preserved.
How would fossils appear in metamorphic rocks?
Because metamorphic rocks are formed by extreme high heat and pressure, they are not good places for fossils to be found. The heat and pressure that metamorphic rocks go through during their formation virtually guarantees that any organism that could attempt to be fossilized with the rock would be destroyed.
Why are most fossils found in metamorphic rocks?
A fossil must be present since the higher temperature and pressure needed to form metamorphic rocks will change the fossil minerals into something else. It is possible for the fossils to remain together but in many cases they are stretched, squeezed, and nearly melted.
What rocks are fossils found in?
Most fossils “hide out” in sedimentary rock . When tiny bits of rocks and minerals (called sediment) join together over millions of years, they become sedimentary rock. Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.
Where are fossils found?
sedimentary rocks
Fossils are mostly found where sedimentary rocks of the right age are exposed, such as river valleys, cliffs and hillsides, and human-made exposures such as quarries and road cuttings.

Plants and animals that become sandwiched in this sediment eventually turn into fossils. Two examples of sedimentary rocks are sandstone and shale.
Why is it unlikely for fossils to be found in metamorphic?
Metamorphic rocks have been put under great pressure, heated, squashed or stretched, and fossils do not usually survive these extreme conditions.
Are metamorphic rocks?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What type of rocks can fossils be found in?
Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.
Are fossils only found in sedimentary rocks?
Of the three types of rocks, only sedimentary rocks can preserve fossils; igneous rocks would destroy fossils before they had a chance to form, and metamorphic rocks would damage fossils due to their heat and/or pressure during formation.
Where metamorphic rocks are found?
We often find metamorphic rocks in mountain ranges where high pressures squeezed the rocks together and they piled up to form ranges such as the Himalayas, Alps, and the Rocky Mountains. Metamorphic rocks are forming deep in the core of these mountain ranges.
