The last-named book deals with radiodating and radiocarbon dating, while the material before you focuses on archaeological dating.The decades when the evolutionists gained final control of Western scientific research.Stratigraphy is the oldest of the relative dating methods that archaeologists use to date things.Stratigraphy is based on the law of superposition--like a layer cake, the lowest layers must have been formed first.Hard water contains less Carbon-14 than the atmosphere, because dissolved carbonates are Carbon-14 free.A fish caught in hard water has thus a higher Carbon-14 age than contemporaneous terrestrial samples.In order to obtain a radiocarbon date, the amount of remaining Carbon-14 atoms in a sample are measured.
The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place.In other words, artifacts found in the upper layers of a site will have been deposited more recently than those found in the lower layers.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.With the introduction of objective quantifiable methods such as dendrochronology and Carbon-14 dating, over the past half century, European and North American archaeology have developed independent and more reliable chronologies, that often make it possible to date more precisely than in Egypt. For Egypt absolute year dates can only be established back to the beginning of the Late Period, from links to Greek chronology, and then from Assyrian king-lists and other Near Eastern sources, back to the Ramesside Period (still debated). The Egyptians dated by the year of reign of the king on the throne (for example 'year 3 of king X').If we knew the precise length of reign for every Egyptian king, chronology would be no problem.An asterisk ( * ) by a name indicates that person is not known to be a creationist.Of over 4,000 quotations in the books this Encyclopedia is based on, only 164 statements are by creationists.Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual. However, only a small number of objects are datable by inscriptions, and there are many specific problems with Egyptian chronology, so that even inscribed objects are rarely datable in absolute terms.In the archaeology of part-literate societies, dating may be said to operate on two levels: the absolute exactness found in political history or 'history event-by-event', and the less precise or relative chronology, as found in social and economic history, where life can be seen to change with less precision over time.“Reservoir age” is the difference between the true age and the Carbon-14 date.The effect, highlighted by the erroneous date from the carbonised residue on Sönkes’ ceramic sherd, persuaded The AMS 14C Dating Centre at Aarhus University in Denmark that they needed to carry out further investigations.
