A new method for dating well-bleached sediments is presented, with results for thirteen samples from china the method uses an isochron constructed from the measurement of natural radiation doses received by potassium-feldspar grains in a range of grain sizes using the infrared stimulated luminescence (irsl) signal. In the mathematical theory of dynamical systems, an isochron is a set of initial conditions for the system that all lead to the same long-term behaviour. Isotope geochem notes: rb-sr an isochron can be saved by removing one or two minerals that are examples of ar dating:.
Isochron dating system so the slope of the line can calculate a numerical age if the values are scattered then the sample is unreliable and will produce an. Hands-on introduction to using the isochron method to determine radiometric questions related to radiometric dating: the radiometric age of a sample. Key flaw found in radioisotope isochron dating for example, carbon (symbol c) is element 6 because it has six protons in every one of its atoms.
