The advantage of isochron dating as compared to simple radiometric dating techniques is that no assumptions are needed about the initial amount of the daughter nuclide in the radioactive decay sequence.
Indeed, the initial amount of the daughter product can be determined using isochron dating.
talk.origins is a Usenet newsgroup (discussion group) which provides defenses for the evolutionary perspective against the creationist perspective.
Its purpose is to be a place about the discussion of issues that relate to the origins of the universe, life on Earth, and civilization, with evolutionary biology, creationism, geology, and Velikovskyanism being the most commonly discussed subjects.
Thus, at the moment of crystallization, the ratio of the concentration of the radiogenic isotope of the daughter element to that of the non-radiogenic isotope is some value independent of the concentration of the parent.
The TO archive also makes a point to link back to pages with opposing viewpoints, something not as common among creationist pages.
Isochron dating is a common technique of radiometric dating and is applied to date certain events, such as crystallization, metamorphism, shock events, and differentiation of precursor melts, in the history of rocks.
Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks (meteorites).
One useful feature of the site is their voluminous list of FAQ files, where creationist and other pseudoscientific claims are carefully debunked.
The sheer quantity of quality scientific information has led to the Talk.
This amount is often unknown and is one of the downfalls of conventional radiometric dating.
