Contrast the usefulness of absolute and relative dating techniques

Age of deposition should not be confused with the date of material enclosed in deposit.

This is a method that does not find the age in years but is an effective technique to compare the ages of two or more artifacts, rocks or even sites.

Anything can be dated relatively, providing suitable field relationships exist Fossils are often used for the relative dating of sedimentary sequences, and in some cases offer exceptionally high resolution correlation - fossils are almost never used for absolute dating.

Both: Both relative and absolute dating can be used to determine the relative age of some events: e.g.

This means that the oldest are the strata that are lying at the bottom.

However, age of deposition does not mean the age of artifacts found in that layer.
