Igneous rocks are formed from magma and were - at one time - hot enough to melt, then they often moved all over the place, once molten. Any fossil would have burned away or disintegrated by the movement. Organisms do not normally survive intact because of the intense temperatures.
Fossils are most unlikely to be found in igneous rocks because they cannot survive through the process of formation of magma.
Most fossils are preserved plant or animal bodies living in or near water. There are no animals or plants which can live in molten magma so you will never find them in cooled magma, which is an igneous rock. There are however, exceptions. For example, where a lava flow covers a tree. The tree is burnt but the impression of it remains in the rock.
Igneous rocks and most metamorphic rocks, of an igneous origin.
No. In general, there are no fossils in igneous or metamorphic rocks, because the high heat and pressure involved would destroy any fossils. Fossils are almost always found in sedimentary rock.
Granite and basalt are both igneous rocks - they are formed from magma extruded into another rock layer or from expulsion from a volcano. The heat of the cooling rock would completely melt any fossils they came into contact with and destroy them, so you don't see fossils in these rocks.
Because Igneous Rocks was made from magma or lava and Sedimentary Rocks are made found underwater where a bunch of rubbish is lying around and they add them together and Metamorphic Rocks were either from Igneous or Sedimentary Rocks so they could also be filled with fossils.
No, fossils are actually very difficult to find. The majority of fossils found are marine invertebrates. They are usually found in sedimentary rock. However, there is plenty of sedimentary rock that contains no fossils at all.
No, fossils are typically found in sedimentary rocks, not igneous rocks. Sedimentary rocks form from the accumulation and compaction of sediments, which can preserve fossils, while igneous rocks form from the cooling and solidification of molten rock, where fossils are usually destroyed.
No, fossils are typically found in sedimentary rocks rather than igneous rocks. Sedimentary rocks form from the accumulation and lithification of sediments, making them more likely to preserve fossils due to their layered nature. Igneous rocks, on the other hand, form from the cooling and solidification of molten rock and are less likely to contain fossils.
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.
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
Igneous rocks and most metamorphic rocks, of an igneous origin.
Fossils usually form when the remains of an organism are buried gently under sediments which later turn into stone. Intrusive igneous rocks form at depths within Earth where no life is found. Extrusive igneous (volcanic) rocks are so hot when they are deposited that any remains of organisms are usually incinerated. Fossils do occur in volcanic rocks, but very rarely.
No. In general, there are no fossils in igneous or metamorphic rocks, because the high heat and pressure involved would destroy any fossils. Fossils are almost always found in sedimentary rock.
Bones, skin, hair, and muscles can form fossils within sedimentary rocks when the remains are buried and undergo a process called fossilization. Leaves can also form fossils in sedimentary rocks through a similar process. Igneous rocks, being formed from molten magma, are less likely to preserve fossils. Plants can form fossils through a process called carbonization, where their structures are preserved in sedimentary rocks.
Granite and basalt are both igneous rocks - they are formed from magma extruded into another rock layer or from expulsion from a volcano. The heat of the cooling rock would completely melt any fossils they came into contact with and destroy them, so you don't see fossils in these rocks.
