Problems with uranium series dating website
This calls the whole radiometric dating scheme into serious question.Geologists assert that older dates are found deeper down in the geologic column, which they take as evidence that radiometric dating is giving true ages, since it is apparent that rocks that are deeper must be older.
In support of my research, I have maintained a clean laboratory and thermal.55-57, (1987), gives us an idea of the tremendous complexity of the processes that occur when magma solidifies.The general idea is that many different minerals are formed, which differ from one another in composition, even though they come from the same magma.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.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.
Over time, there is ingrowth of Th from the radioactive decay of uranium until radioactive equilibrium is reached where all isotopes in the series are decaying at the same rate.
Most scientists today believe that life has existed on the earth for billions of years.
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.
With a launch date of 22 October, she's hard at work on UCT's new dating laboratory, which builds on UCT's reputation in geochemistry, rooted in the radiogenic isotope facility set up 10 years ago.
