Law of superposition definition. The law of superposition is one of the most fundamental principles of stratigraphy the branch of archeology which studies the geological layers of the earth and soil. A general law stating that in any sequence of sediments or rocks that has not been overturned the youngest sediments or rocks are at the top of the sequence and the oldest are at the bottom. Definition of law of superposition.

Superposition is the name for the observation that given a stack of layers or beds of sedimentary rocks older beds are found below younger beds as long as there has been no disturbance of the. Law of superposition a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence. The law of superposition or the principle of superposition is a key axiom based on observations of natural history that is a foundational principle of sedimentary stratigraphy and so of other geology dependent natural sciences.

On occasion however deformation may have caused the rocks of the crust to tilt perhaps to the point of. This law has a proven record of being able to accurately determine the relative ages of the different layers of soil. If we elaborate the law of superposition in detail it means that the oldest strata lie at the bottom and the newer strata at the top.

As we know that the lowest layer has to be laid down first and so it should be older. Where there has been no subsequent disturbance sedimentary strata were deposited in ascending order with younger beds successively overlying older beds. The law of superposition is an axiom that forms one of the bases of the sciences of geology archaeology and other fields pertaining to geological stratigraphy.

The same rule applies and the layers go on to the uppermost one. A law in geology. Law of superposition definition a basic law of geochronology stating that in any undisturbed sequence of rocks deposited in layers the youngest layer is on top and the oldest on bottom each layer being younger than the one beneath it and older than the one above it.

Sedimentary layers are deposited in a time sequence with the oldest on the bottom and the youngest on the top.
