Stratigraphic dating

The example used here contrasts sharply with the way conventional scientific dating methods are characterized by some critics (for example, refer to discussion in "Common Creationist Criticisms of Mainstream Dating Methods" in the Age of the Earth FAQ and Isochron Dating FAQ).A common form of criticism is to cite geologically complicated situations where the application of radiometric dating is very challenging.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.

A current Cooperative Ecosystems Studies Unit (CESU) agreement with Dr.Swisher, who used 40Ar/39Ar dating methods to provide ages for tuffs within the monument (Swisher 1992).To date, there are 20 radiometrically dated volcanic rock layers that occur within the monument and more layers that have been dated from surrounding areas.Over the last 20 years, knowledge of the stratigraphy and ages of rock units in the John Day Basin has improved dramatically.Multiple researchers have worked in all three units of the monument and surrounding areas to produce a detailed stratigraphic framework for this region. (2008) refined the stratigraphy of the Mascall Formation, while work continues on revision of the stratigraphy of the Rattlesnake Formation begun by Martin and Fremd (2001).

Similarly, materials of human origin are also deposited onto the earth’s surface.
