Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.

How do geologists use fossils to determine rocks age what are this fossils called?
they find the hard part of the fossil
Why is it unlikely to find fossils in marble?
Marble is a metamorphic rock, and the process of metamorphosis destroys fossil shapes.
What happens to a fossil in a metamorphic rock?
Not normally. Metamorphism destroys the characteristics of the original rock, including bedding, cleavage, texture and fossils. In extremely low grade metamorphic rocks, however, fossils may still be present, however these fossils will be deformed.
What aren't you likely to find a fossil I metamorphic rock or igneous rock?
The fossils will be crushed under the pressures required to create metamorphic rocks and they will melt in the heat required to make igneous rocks.
Why do you seldom find fossils in metamorphic rocks?
As metamorphic rocks form under large pressure and temperature, the original composition of the rock is largely lost. Take for example marble, with it's protolith (original rock) being limestone. Limestone contains a lot of fossils, however, when it's put under pressure, the fossils collapse, the calcium inside dissolves in the water that is present in the rock, and settles at different places again. All this makes sure that you can't actually see the fossils in the marble. It's still the same material, but it's deformed too strong to see the fossils.
Can you find broken fossils in metamorpic rocks?
yes you can find broken fossils in metamorphic rics
How do geologists use fossils to determine rocks age what are this fossils called?
they find the hard part of the fossil
What kinds of rocks do you not find fossils in and why?
Igneous rocks and metamorphic rocks, because the intense heat and pressure destroys fossils.
In what type of rocks could you find fossils?
Fossils are principally found in sedimentary rocks and also in some metamorphic rocks of sedimentary origin.
Would you find fossils in metamorphic rock?
You can but it very very rare. you are more likely to find them in sedimentary rocks.
Why don't you usually find fossils in metamorphic rocks?
because of the heat and pressure that wrecks and deforms it.
Why are you likely to find fossils in evaporite sedimentary rocks but not in detrital sedimentaryor metamorphic rocks?
Yes
Would you be less like to find fossils in metamorphic rocks than in sedimentary rocks?
Yes.
Would you be less likely to find fossils in metamorphic rock than in sedimentary rock?
Yes.
