Principe de superposition (géologie)
These methods require the elaboration of reliable criteria and the constitution of tools and references of a chrono-typological nature. The examples presented in this article suggest that beyond the mere accumulation of information on the heritage of this territory, the inventory campaigns, through their chronological analyses, make a real contribution to the interpretation of the history of the French countryside.

Relative dating is the science of determining the relative order of past events i. In geology, rock or superficial deposits , fossils and lithologies can be used to correlate one stratigraphic column with another. Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating , archaeologists and geologists used relative dating to determine ages of materials. Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique. Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.
