What is stratigraphy dating
Stratigraphy, scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale.It provides a basis for historical geology, and its principles and methods have found application in such fields as petroleum geology and archaeology.While this is very good, this is only a fraction of what is available for dating, and some large sections of the stratigraphic column do not have any volcanic rock layers dated.A current Cooperative Ecosystems Studies Unit (CESU) agreement with Dr.
An important principle in the application of stratigraphy to archaeology is the law of superposition—the principle that in any undisturbed deposit the oldest layers are normally located at the lowest level.
Accordingly, it is presumed that the remains of each succeeding generation are left on the debris of the last.
Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.
Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first.
In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.
