Relative dating and absolute dating similarities discreet dating in orangeville
The greatest problem with dating an artefact from an archaeology site is that nearly every absolute dating process requires the destruction of at least a piece of the object in conducting the analysis. There are relatively few dating laboratories and having an artefact dated can be an expensive exercise especially if the artefact is not of great value itself. The underlying principle of stratigraphic analysis in archaeology is that of superposition.This term means that older artefacts are usually found below younger items.C14 Radiocarbon dating can only be used on organic matter.Lithic items cannot be dated by C14 radiocarbon methods but the same principle can be used using radioactive uranium.Rocks, when formed by volcanic reaction or other cataclysmic event, contain a minute quantity of radioactive substance.From the day of the rock's creation this radioactivity begins to deplete.
Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating.
Once an artefact is compared to its known development date then whenever that item reappears in the archaeological record, of that or any other site, it can quickly be dated.
The potential flaws in relative dating in archaeology are obvious.
At the moment of death the C14 begins to decay at a rate that scientists already know from other experiments.
The missing amount can then determine how long it took to be lost and therefore date the object to a precise period.
The shape and style of an artefact changes through time although its function may remain the same.
