Field geologists always prize a layer that is so distinctive in appearance that a series of tests need not be made to establish its identity. While absolute ages require expensive, complex analytical equipment, relative ages can be deduced from simple visual observations. Nevertheless, there is no greater testimony to the validity of fossil-based stratigraphic geology than the absolute dates made possible through radioactive measurements.

Fossils and relative dating

In order to communicate the fine structure of this so-called column, it has been subdivided into smaller units. In the ideal case, the geologist will discover a single rock unit with a unique collection of easily observed attributes called a marker horizon that can be found at widely spaced localities. For example, the presence of recycled bricks at an archaeological site indicates the sequence in which the structures were built.
