QUESTION: What is the difference between relative and absolute dating techniques?ANSWER: In relative dating, something is determined to be older or younger than something else without determining an exact age.It is hard to think that this is a coincidence; it is also hard to think of any mechanism that could produce this agreement other than that the rocks are as old as radiometric methods tell us.We began our discussion of absolute dating by saying that sedimentation rates could not be relied on for absolute dating.

For example, if an artefact, say an oil lamp, is found co-located on the same floor of a governor's dwelling, and that floor can be dated in archaeology terms by reason of the patterns employed in the mosaic, then it is assumed that in relation to the floor that the lamp is of the same age.

Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact's likely age.

Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.

Since relative dating can easily be verified by superposition (the younger bed over the older one), intrusion (the intrusive being younger than the intrusive rock), and use of index fossils (younger fossils in a rock layer make that layer younger than another containing older fossils), relative dating can be confirmed right at the field using one's direct observation.

It could also be immediately confirmed in the base office once maps and cross sections are updated and the rock units confirmed.
