Neither. You can get sedimentary rocks that are older than igneous rocks, or igneous that are older the sedimentary rocks. However, igneous rocks are formed from magma within the earth's crust, or as it extrudes onto the surface, while sedimentary rocks are formed from the erosion and redeposition of existing rocks, so generally in the life cycle of a rock the igneous form would come first.

Name the 3 kinds of rocks?
The three main types of rocks are igneous, formed from cooling lava or magma; sedimentary, formed from compressed layers of sediment; and metamorphic, formed from existing rocks that undergo high heat and pressure.
Is graphite igneous sedimentary or metamorphic?
Graphite is a metamorphic rock. It is formed from the metamorphism of organic sedimentary rocks, such as coal, under high temperature and pressure.
What are the three types of rocks involved in the rock cycle?
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.
Are stalactites and stalagmites igneous or sedimentary?
They are chemicAL Sedimentary rock
Is aluminum igneous sedimentary or metamorphic?
Aluminum is not classified as igneous, sedimentary, or metamorphic. It is a metallic element and is naturally found in the Earth's crust, often in combination with other elements or minerals.
To date a sedimentary rock layer between two igneous rock units geologists use radiometric dating and assume that the sedimentary layers are?
Geologists use radiometric dating of the igneous rock units above and below the sedimentary layer to establish a time range for the sedimentary rock. They assume that the sedimentary layers are younger than the underlying igneous rock and older than the overlying igneous rock, based on the principle of superposition. This allows them to estimate the age of the sedimentary layer by determining the ages of the surrounding igneous rocks.
What Type Of Rock Is The Oldest Metimorfic Igneous Or Sedimantary?
Metamorphic rocks are generally considered the oldest type of rock because they form from the alteration of existing rocks—either igneous, sedimentary, or even older metamorphic rocks—under heat and pressure. While igneous and sedimentary rocks can also be ancient, the processes that form metamorphic rocks often involve these older types. Therefore, in terms of geological history, metamorphic rocks can be older than both igneous and sedimentary rocks.
What is the name of all three rocks sedimentary igneous and?
Sedimentary, igneous and metamorphic.
Is mudstone igneous or sedimentary?

How did metamorphic rocks get to be on the earth today?
Metamorphic rocks are older sedimentary, igneous, and metamorphic changed by pressure and temperature.

What is the process sedimentary to igneous?
In order to get an igneous rock from a sedimentary rock, the sedimentary rock must be melted and then that melt must crystallize.
