Radiometric isochron dating
The slope of the line is related to the age of the samples.The simplest way to think of it is this: Some rock materials (isotopes) decay, and we can determine the age of a rock in today’s laboratories by determining how much of a specific isotope contained in the rock has decayed.There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.According to theory, the sample starts out with daughter isotopes present at constant ratios in relation to one another, but with the parent isotope the ratio is arbitrary.
Like Nimrod of ancient times, they know they must provide an alternative (i.e., naturalism, specifically —the belief that science alone can render truth about our world and reality) to biblical truth if they are to hold sway over the public in what is essentially a couched rebellion against God.
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.
This serves as strong evidence for the reliability of radiometric dating methods. These isotopes differ in the number of neutrons they have in their nuclei.
Those isotopes that are not stable decay into daughter nuclei.
