Metamorphic rock is formed deep in the Earth's crust under tremendous heat and pressure. Fossiles are formed in sedimentary rock near the surface.
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
Marble is a metamorphic rock, and the process of metamorphosis destroys fossil shapes.
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.
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.
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.
yes you can find broken fossils in metamorphic rics

Igneous rocks and metamorphic rocks, because the intense heat and pressure destroys fossils.
If the rock type around your home is primarily metamorphic, you are unlikely to find many fossils. Metamorphic rocks form under high pressure and temperature, which typically destroys any fossils that might have been present in the original sedimentary rock. Fossils are more commonly found in sedimentary rocks, where the conditions are conducive to preserving organic remains. Therefore, the chances of finding fossils in metamorphic rocks are minimal.
Fossils are principally found in sedimentary rocks and also in some metamorphic rocks of sedimentary origin.
You can but it very very rare. you are more likely to find them in sedimentary rocks.
Yes
Yes.
Yes.
because of the heat and pressure that wrecks and deforms it.
i dont no
Index Fossils
