Potassium dating accuracy

The potassium-argon dating method has been used to measure a wide variety of ages.The potassium-argon age of some meteorites is as old as 4,500,000,000 years, and volcanic rocks as young as 20,000 years old have been measured by this method.In a related article on geologic ages (Ages), we presented a chart with the various geologic eras and their ages.

Developed in the 1950s, it was important in developing the theory of plate tectonics and in calibrating the geologic time scale.Firstly: please try not to bring creation/evolution into this.I will award the correct answer to a response which provides links to evidence and sound explanations.The slope of the line determines the date, and the closeness of fit is a measure of the statistical reliability of the resulting date.Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.
