A portion of the material is ground up and a measurement is made of the ratio of radioactive “parent” atoms to the decomposition products.
Age estimates which are obviously wrong or contradictory are sometimes produced.
A popular and supposedly foolproof method was used on two lava flows in the Grand Canyon that should be ideal for radioactive age estimation. Young basalt rock at the Canyon's top produced an age estimate 270 million years older than ancient basalt rock at the Canyon's bottom.
The problem seems to arise from basic wrong assumptions in the method (rubidium-strontium isochron).
The Carbon-14 age estimating method is, at best, only useful for estimating the age of things that are thousands of years old, not millions or billions.
And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.
Uncalibrated radiocarbon dates should be clearly noted as such by "uncalibrated years BP", because they are not identical to calendar dates.
The ages are expressed in years before present (BP) where "present" is defined as AD 1950.
A radioactive form of potassium is found in minute quantities in some rocks.
It disintegrates at a measured rate into calcium and argon.
Such ‘confirmation’ may be shortlived, as nature is not to be discovered quite so easily.
There has been in recent years the horrible realization that radio-decay rates are not as constant as previously thought, nor are they immune to environmental influences.
