Stratigraphic dating meaning


Applying the principle of superposition, we know that Stratum A was deposited after Stratum B, Stratum B was deposited after Stratum C, and so on. Without additional information, however, we cannot assign specific dates or date ranges to the different episodes of deposition. In this example, archaeologists might radiocarbon date the basket fragment or bone awl in Stratum E, and they could use artifact seriation to obtain fairly precise date ranges for Strata A, B, C, and E. If the date on the car license plate is preserved, they can say with certainty that Stratum A was deposited in that year or later.

Archaeologists map the cultural and natural layers that they see in a site to better understand the processes that created the site and the changes that occurred over time.

Computer models can be used to estimate the age along an ice core, . when the annual layers are too thin to be counted or to give a quick estimate of the depth-age relationship of an ice core. The models describe the flow of the ice, taking into account the amount of annual snow fall and how the layers are being compressed and deformed by the burden of the snow and ice above.
