  Stratigraphy - Wikipedia, the free encyclopedia
One of stratigraphy's basic concepts is codified in the Law of Superposition, which simply states that, in an undeformed stratigraphic sequence, the oldest strata occur at the base of the sequence.
The study of stratigraphic sequences has led to some important results and given rise to the discipline of sequence stratigraphy, such as the Vail curve, which attempts to define a global historical sea-level curve according to inferences from world-wide stratigraphic patterns.
Stratigraphy is also commonly used to delineate the nature and extent of hydrocarbon-bearing reservoir rocks, seals and traps (see petroleum geology).

 Archaeology - Wikipedia, the free encyclopedia
Modern excavation techniques require that the precise locations of objects and features, known as their provenance or provenience, be recorded.
For example, excavation of a site reveals its stratigraphy; if a site was occupied by a succession of distinct cultures, artefacts from more recent cultures will lie above those from more ancient cultures.
There are many different styles of excavation, with some countries traditionally preferring one method over another; and some sub-disciplines like classical archaeology will often use different methods than those used for the excavation of a prehistoric site.
