Law of Superposition – Determining the relative ages of undisturbed sedimentary rocks

Geology’s Law of Superposition states that the oldest and youngest layers of sedimentary rock layers are at the bottom of an undisturbed sequence. You can use this principle to calculate the relative age of an undisturbed sedimentary rock sequence. Geologists employ the law of Superposition to determine the relative age of an undisturbed sedimentary rock sequence. This states that the oldest layers are at the bottom, while the youngest will be at top. (Lubin 2016, 2016). Outcrops are an example of this principle. The oldest rocks can be found at the bottom, while the youngest are at the top. Other relative dating methods, such as inclusions and cross-cutting relationships or fossil correlation, can be used by geologists to establish the rock’s relative age. Geologists must identify both the oldest and youngest layers of rock at the bottom to apply superposition in order to calculate the relative ages for the undisturbed sedimentary sequence (Lubin 2016, 2016).
