A group of researchers from Oxford University has published its recent research in Science Journal, as per a report, which claims to have a precise record for dating materials. The source, as the team says, is Lake Suigetsu in Japan.
It has been told that a wide range of radiocarbon measurements was discovered from the lake, which helped it find a benchmark, in particular for older objects.
Previously, some researchers, say far back as 1993, had identified sediment cores would prove a great help in radiocarbon dating. But, technical problems did not let the initial efforts go successful. However, this time cores of preserved sediment layers have been extracted by the team.
These are the spots from where the layers had reclined for thousands of years on the Lake Suigetsu's bottom. Also, these cores carried tree leaf or twig fossils-like organic material. And it is being said that more accurate way is available with the study, if organic material's radiocarbon ages for the 11,000 - 53,000-year time range is to be determined.
"The new results offer an important refinement of the atmospheric radiocarbon record and place the radiocarbon timescale on a firmer foundation", Senior Editor at Science Jesse Smith has affirmed.
