Radiohalo dating

16 Jul

It was concluded that the regional metamorphism, the hydrothermal fluid flows, the cooling of the regional metamorphic complex, and the formation of the Po radiohalos all had to have occurred within a few weeks.This is feasible in the context of catastrophic plate tectonics and grossly accelerated U and Po radiohalos frequently found together in biotite flakes in granitic rocks had to have formed simultaneously (Snelling 2005).

So, I switched to other challenges, since ICR was better equipped and positioned to meet the challenge of radioisotopes.Radiocarbon is not suitable for this purpose because it is only applicable: a) on a time scale of thousands of years and b) to remains of once-living organisms (with minor exceptions, from which rocks are excluded).MYTH #2 Radiocarbon dating has established the date of some organic materials (e.g., some peat deposits) to be well in excess of 50,000 years, thus rendering a recent creation (6 to 10 thousand years ago) impossible.Because of the very short half-lives of the parent Po isotopes, this implies that hundreds of million of years worth of U radiohalos) and the 500 million–1 billion polonium atoms required to generate the polonium radiohalos.Radiometric dating or radioactive dating is a technique used to date materials such as rocks or carbon, in which trace radioactive impurities were selectively incorporated when they were formed.
