law of superposition
A general law upon which all geologic chronology is based: In any sequence of sedimentary strata (or of extrusive igneous rocks) that have not been overturned, the youngest stratum is at the top and the oldest at the base; i.e., each bed is younger than the bed beneath, but older than the bed above it. The law was first clearly stated by Steno (1669).
