Absolute dating is the process of determining a specific date for an archaeological or palaeontological site or artifact.
Some archaeologists prefer the terms chronometric or calendar dating, as use of the word "absolute" implies a certainty and precision that is rarely possible in archaeology.
This is a radiometric technique since it is based on radioactive decay. " Serianne Worden (Columbia University) beams over a piece of pottery in the fill of an obsolete tank in the "Soap Factory." Nearly all of the industrial tanks we have excavated are adjacent to the threshold, in close proximity to the path of curious tourists. When possible, fractured pieces are rejoined in their original configuration, as was this platter held by Louise Ford (University of Bradford). A crater in the city wall behind marks the point of impact one such ball may have made in 89 B. Burns is currently a doctoral student at University College London, where he is writing a dissertation on Roman warfare. All ceramic samples are carefully sorted, catalogued, illustrated, and studied by pottery specialists.Absolute dating, on the other hand is capable of telling the exact age of an item using carbon dating and many other techniques that were not there in earlier times.Relative dating makes use of the common sense principle that in a deposition of layers.The deposit thus occurring forms layers depending on the nature of the material brought in by the people inhabiting the area.
