The Iconic Isochron: Radioactive Dating, Part 2, The Institute for Creation Research
Isochron Dating as a Current Scientific Clock By Calvin Krogman Radioactive decay has become one of the most useful methods for determining the age of formation of rocks.
However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid. These assumptions include: 1 the initial amount of the daughter isotope is known, 2 neither parent or daughter product has migrated into, or out of, the closed rock system, and 3 decay has occurred at a constant rate over time.
But what if one or some combination of these assumptions is incorrect? Then the computed age based on the accumulation of daughter products will be incorrect Stasson In order to use the valuable information provided by radiometric dating, a new method had to be created that would determine an accurate date and validate the assumptions of radiometric dating.

For this purpose, isochron dating was developed, a process "that solves both of these problems accurate date, assumptions at once" Stasson A natural clock must meet four requirements. Isotope dating satisfies this requirement, as daughter products do not decay back to the original parent element.
It has been established through extensive experimentation that radioactive decay occurs at a constant rate. In this case, the initial condition is the amount of daughter isotope in the rock when it was formed. This amount is often unknown and is one of the downfalls of conventional radiometric dating.
However, isochron dating bypasses this assumption, as explained below. The final condition is the number of atoms of parent and daughter isotopes remaining in the rock and can easily be measured in a lab.

Isochron dating bypasses the necessity of knowing the quantity of initial daughter product in the rock by not using that value in the computation. Instead of using the initial quantity of isochron dating problems isotope, the ratio of daughter isotope compared to another isotope of the same element which is not the product of any decay process is used as the comparison for isochron dating. The plot of the isochron datings problems of the number of atoms of the parent isotope to the number of atoms in the non-daughter isotope compared to the number of atoms of the daughter isotope to the non-daughter isotope should result in a straight line that intersects the vertical y-axis which is the ratio click daughter to non-daughter isotopes.
This point of intersection gives the initial ratio of daughter to non-daughter isotopes, which would also be the ratio in a mineral that crystallized without any parent isotope present. According to Brent Dalrymple"the trick to the isochron diagram is the normalization of both parent and daughter isotope to a third isotope. In the initial state, the graph of daughter isotope to the third isotope versus parent isotope to the third isotope should result in a straight, horizontal line.
The process of evaluating the daughter product as a ratio against another isotope of the same element is a valid method because, when a mineral or rock forms from a homogenous isochron dating problems, the elements that are assimilated into crystalline formation are very restricted. The key to the formation of crystals in the rock is that the process is selective between elements, but is indifferent to isotopes of the same element.
Thus, the daughter product and any other isotopes of the same element will be incorporated into the minerals of a rock with the same ratio.
We see why we can't date any rock as they must satisfy the requirements of absolute radiometric dating. Before ending with which types of rocks best suit.
This initial ratio allows the non-daughter product isotope to be representative of the initial amount of the daughter product Stassen The amount of non-decay isotope in the sample does not change. Thus, as decay occurs, the parent.
