Dating techniques used in archaeology
It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself.Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology, archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.Nuclear physics is important in a vast variety of situations, from understanding how the Sun provides the energy for life on this planet, to nuclear power plants and radiation therapy.Without nuclei, we simply would not exist, and it is important to understand why!
Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.The sequence of development of culture or the relationship between events that represent culture can be established only when events can be placed in proper time.Chronology, the study of events in time frame, is hence the central theme of archaeologist, like the geologist who deals with the story of earth history.(Examples of each method, respectively, are dendrochronology, carbon-14, archaeomagnetism, and the known year a city was destroyed.) Relative dating is based on stratigraphy (the tendency of younger layers to lie over older layers) and comparison of artifacts from undated sites to sites where dates are established.All dating methods have limitations and can be complicated by turbation, or mixing, of layers by human or natural actions.
