We develop a statistical model for age uncertainties in stratigraphic cores that treats the true, but in practice unknown, ages of core samples as random variables.
For inaccuracies in the ages of tie points, we draw the error from a zero-mean normal distribution.
Learn how inclusions and unconformities can tell us stories about the geologic past.
We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.
Two broad categories of dating or chronometric techniques that archaeologists use are called relative and absolute dating.
Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things. Time series analysis of individual or combined records is commonly employed to seek quasi-periodic components or characterize the timescales of relevant physical processes. Limitations on stratigraphic analyses due to incomplete age control and their relevance to sedimentary paleomagnetism. Records derived from diverse locations are often compared or combined to construct records that represent a global signal.The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.For example, JJA Worsaae used this law to prove the Three Age System.Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.
