An igneous rock is formed when molten rock solidifies.

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.
