Radiocarbon dating how reliable five languages love dating
Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.The latest high-tech equipment permits reliable results to be obtained even with microscopic samples.For example, creationist writer Henry Morris [Morris2000, pg.147] has highlighted the fact that measurements of specimens from a 1801 lava flow near a volcano in Hualalai, Hawaii gave apparent ages (using the Potassium-Argon method) ranging from 160 million to 2.96 billion years, citing a 1968 study [Funkhouser1968].
In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.
Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (an "isochron") by means of standard linear regression methods of statistics.
The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.
We conclude thattufa samples give reproducible data within the time span of ≈ 40,000 years up torecent.
The 14C/12C ratio of carbon in the ambient biosphere and hydrosphere gives adetailed picture of the distribution of carbon isotopes in the investigated system.
