Probably because both igneous and metamorphic rocks are formed by means other that don't allow for fossils to be preserved.For example, igneous rocks iare made of cooled magma and the only way a fossil would emerge would be through falling into the magma and not melting.
I would not call it "rare" but it's not very common. It's metamorphosed limestone so associated with major orogenies.
Their composition of soft materials.
the amber will envolve into a aratactol and the others r not realy that good but thetre rare hope that helps you
Yes, rhyolite is considered rare. It is considered rare because it is considered a type of advanced igneous volcanic rock.
Volcano lava forms as rocks as it cools down. Rocks are formed with magma and lava which when cooled down would form as rough matters. Rare lava parts are formed up like ruby, diamonds, and even emeralds.
A lamprophyre is a type of ultramafic intrusive igneous rock. It is very rare for fossils to be formed in igneous rocks (and they usually only form as mold fossils in extrusive deposits). As such fossils will not form in lamprophyres.
Though somewhat rare, either rock type could contain fossils.
fossils almost allways occur in sedementary rock. this is the only way to get fossils without burning or cruching the fossil. you sometimes get fossils in igneous rock, but this is very rare. igneous rock fossils do not have any actual "fossils" in them, they are just impressions.
This is because igneous and metamorphic rocks are created under extreme heat and pressure, and very few fossils would survive those conditions. The most common forms of fossils are those found in sedimentary rocks.
Marble is metamorphosed limestone.
Fossils abound in sedimentary rock, you are in fact very likely to find them there.

because fossils are rare to find and in complete form even more rare only 10% or less out of 100% fossils have been found on earth
Generally, fossils are found in sedimentary rocks because other rocks (igneous and metamorphic) would expose fossils to too much heat while the rocks formed. However, there are rare exceptions to this.
Yes. I found 3completely rare fossils by digging.
Yes, fossilisation is a rare process especially on land. There will have been many species not preserved as fossils but it would be impossible to prove as there are no remains. It is also possible that many species were preserved in rocks but, due to tectonic processes, they were obliterated as the rocks were metamorphosed.
