Archaeologists use changes in trends to figure out how old a site is based on the style of artifacts they find.This is a type of relative dating known as seriation.One fashion style might be new and unpopular at first, but soon everyone is wearing it.Then, one day, the baggy neon sweater you used to love is no longer trendy and gets replaced by shoulder pads!You probably have a good idea of which ones are older even if you don’t know anything about cars. Chances are, you can tell the 1981 Honda Accord apart from the 2014 model just by looking at them! If you saw someone wearing a baggy neon sweater you can be sure they bought it in the 1970s.That’s because the things that people make and use change in appearance over time. Not all tree species are sufficiently sensitive to display distinctive variations in their ring characteristics, particularly when growing in temperate climates. Without doubt, it has made the greatest single contribution to the development of archaeology since geologists and prehistorians escaped from the constraints of historical chronology in the nineteenth century. ----- The application of tree-ring dating Unfortunately there are many problems in the direct application of dendrochronological dating. Potassium-argon (40K/40Ar) and argon-argon dating (40Ar/39Ar) 4.5.6. ----- The impact of radiocarbon dating Radiocarbon dating has grown exponentially, and many problems and inaccuracies have been isolated and examined, some leading to major adjustments of the results.

Relative dating does not give archaeology absolute dates that can be tied into a calendar.Archaeology can be defined as “the scientific study of the human past, of ancient human behaviour, from the earliest times right up to the present.”(Fagan, 2006) .The study of archaeology as an academic discipline is dependant on the accuracy of various dating methods.Adding the margin of error for carbon-14 (in this case, /- 150 years), the archaeologist can give a reliable date range for the bone: 1655-1405 B. A bone found deep in the ground will generally be older than one found close to the surface, for example.Two bones found in the same archaeological deposit are likely to be the same age.

TYPOLOGY AND CROSS-DATING It must be made clear at the outset that typology is not, strictly speaking, a dating method, but a means of placing artefacts into some kind of order. Climatostratigraphy :: Seabed deposits :: Ice cores 4.4.3. SCIENTIFIC DATING TECHNIQUES The transformation of archaeological dating that began around 1950 continues, but archaeologists may overlook the revolution in scientific dating that had already taken place in geology during the first half of the twentieth century; from this wider perspective, the emergence of radiocarbon dating may seem slightly less dramatic 4.4.1.
