Radiocarbon dating and the
Tephrochronology: Within hours or days of a volcanic eruption, tephra — fragments of rock and other material hurled into the atmosphere by the event — is deposited in a single layer with a unique geochemical fingerprint.
Researchers can first apply an absolute dating method to the layer.
Based in Miami, Florida, the Beta Analytic radiocarbon dating lab revolutionized the fields of archaeology and late quaternary geology. (Universite de Paris Sorbonne) and Jerry Stipp, Ph. The company’s dedication to accuracy is at the core of its policies.
Prior to the company’s inception in 1979, radiocarbon dates were scarce and available only through small university laboratories. By innovating new techniques, keeping abreast of the latest technology, and training qualified scientists to stay ahead of demand, Beta Analytic has maintained its firm commitment to quality over the years.
The good dates are confirmed using at least two different methods, ideally involving multiple independent labs for each method to cross-check results.
Sometimes only one method is possible, reducing the confidence researchers have in the results. “They’re based on ‘it’s that old because I say so,’ a popular approach by some of my older colleagues,” says Shea, laughing, “though I find I like it myself as I get more gray hair.” Kidding aside, dating a find is crucial for understanding its significance and relation to other fossils or artifacts.
Unlike observation-based relative dating, most absolute methods require some of the find to be destroyed by heat or other means.The lab does not engage in “satellite dating” – the practice of preparing individual graphite samples in remote chemistry labs then subcontracting to an AMS facility for the measurement.Secure online access to results, sample photos, and quality assurance reports Clients have online access to results from any device and can download calibration and QA reports 24/7 via the mobile-responsive results portal on the lab’s website.About AMS Dating Accelerator Mass Spectrometry (AMS) dating involves accelerating ions to extraordinarily high kinetic energies followed by mass analysis.
Radiocarbon Dating Groundwater The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited.All packages shipped to these offices are forwarded to Miami, Florida, via overnight courier service at Beta Analytic’s expense.
