Fifty Years of Radiocarbon Dating
The history of radiocarbon dating through the 20th century is presented, focusing on the work of Willard F. Libby, who introduced radiocarbon dating in 1949, and its application during the following 50 years. Topics include an explanation of radiocarbon dating, by which the age of organic matter can be determined; difficulties Libby encountered in developing processes for accurate measurements;...
متن کاملConstructing deposition chronologies for peat deposits using radiocarbon dating
Radiocarbon dating is one of the main methods used to establish peat chronologies. This article reviews the basis of the method and its application to dating of peat deposits. Important steps in the radiocarbon dating procedure are described, including selection and extraction of material (and fractions) for dating, chemical and physical preparation of media suitable for measurements, measureme...
متن کاملRadiocarbon Dating of Bone Apatite by Step Heating
Many advances have been made in radiocarbon dating of bone organics, but research on 14C dating of bone inorganic carbon has lagged significantly behind. Using mammoth bone, enamel, and tusk from the Dent and Murray Springs Clovis sites, experiments with the Haas and Banewicz technique of bone apatite dating by step heating demonstrate that accurate radiocarbon ages can be produced from bone ap...
متن کاملIntroduction to Radiocarbon Determination by the Benzene Method
Note References below that are in red italics indicate published methodology works by M.A. Tamers Ph.D., D.Sc. and J.J. Stipp Ph.D., owners of BETA Analytic Inc., who were among the originators of the Benzene Method of Radiocarbon Dating. Between the two of them they have published well over 100 articles on geochronology and research related to the Benzene Method of Radiocarbon dating. An addit...
متن کاملRadiocarbon Dating in Near-eastern Contexts: Confusion and Quality Control
Near-Eastern archaeology has long remained oblivious to radiocarbon dating as unique historical calendars brought about a perception that 14C dating is superfluous. Circular chronological reasoning may occur as a result. There is now strong 14C evidence that the early part of Egyptian history seems older than age assessments currently in vogue among scholars. It is vital to apply systematic and...
متن کاملRadiocarbon Dating of Ground Water
Radiocarbon dating of ground water is used in combination with the primary measurements of classical hydrological and chemical analyses. Radiocarbon dating will produce the best results when it involves multiple measurements or sequential sampling. The most useful data come from these comparisons and not from absolute ages. In the case of multiple measurements, the apparent ages of the ground w...
