Radiometric dating system
Here I want to concentrate on another source of error, namely, processes that take place within magma chambers.To me it has been a real eye opener to see all the processes that are taking place and their potential influence on radiometric dating.Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object.Most scientists today believe that life has existed on the earth for billions of years.Most people are not aware of the many processes that take place in lava before it erupts and as it solidifies, processes that can have a tremendous influence on daughter to parent ratios.Such processes can cause the daughter product to be enriched relative to the parent, which would make the rock look older, or cause the parent to be enriched relative to the daughter, which would make the rock look younger.This belief in long ages for the earth and the existence of life is derived largely from radiometric dating.
Understand how decay and half life work to enable radiometric dating.
This calls the whole radiometric dating scheme into serious question.
Radiometric dating is largely done on rock that has formed from solidified lava.
Lava (properly called magma before it erupts) fills large underground chambers called magma chambers.
This age is computed under the assumption that the parent substance (say, uranium) gradually decays to the daughter substance (say, lead), so the higher the ratio of lead to uranium, the older the rock must be.
Of course, there are many problems with such dating methods, such as parent or daughter substances entering or leaving the rock, as well as daughter product being present at the beginning.
