What else can I help you with?
Is marble an extrusive or an intrusive rock?
Neither. The terms intrusive and extrusive apply to igneous rocks; marble is metamorphic.
Do igneous rocks usually contain fossils?
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.
Are fossils found in sedimentary and metamorphic rocks?
no, fossils are found only in sedimentary rock.
Is it true that igneous rocks form only beneath earths surface?
No, igneous rocks can form both beneath and above the Earth's surface. Intrusive igneous rocks form beneath the surface as magma cools and solidifies underground. Extrusive igneous rocks, on the other hand, form on the Earth's surface when lava cools and solidifies quickly.
Why can’t fossils be formed in metamorphic rock and only in sedimentary rocks and igneous rocks as they cool?

Does lamprophyre form 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.
Are extrusive rocks igneous rocks?
Yes! extrusive means that the igneous rock was forced to the surface at one time. not only are lava flows extrusive but also cinders and pumice that was airborn during eruption
Is marble an extrusive or an intrusive rock?
Neither. The terms intrusive and extrusive apply to igneous rocks; marble is metamorphic.
Are metamorphic rocks volcanic?
No. Only extrusive igneous rocks are volcanic.
Do igneous rocks usually contain fossils?
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.
Is coal an extrusive or an intrusive?
Coal is neither extrusive nor intrusive. Coal is a sedimentary rock that forms from the accumulation and compaction of plant material over millions of years. It is typically found near the Earth's surface in sedimentary basins and is not formed through volcanic or igneous processes like extrusive or intrusive rocks.
Would you find fossils in igneous rocks?
Yes, but only "Mold" type fossils, that is fossils that are an impression of the original object. Examples can be found at Lava Tree natural park in Hawaii. In this case there are trees that are surrounded by lava that burns away the tree within while leaving a hollow impression of the tree. There are multiple examples of fossilized remains found in various ash based Tuffs, specific examples are Pompeii and Herculanium the voids found in the ash flow, multiple fossilized footprints.
What types of rocks contain fossils?
Igneous rocks and most metamorphic rocks, of an igneous origin.
Are igneous rocks formed only beneath earth's surface?
No. Intrusive igneous rocks are formed beneath the earth's surface when magma cools and extrusive igneous rocks form when lava extrudes from a volcano and cools.
Are fossils found in sedimentary and metamorphic rocks?
no, fossils are found only in sedimentary rock.
