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.Radiometric dating is largely done on rock that has formed from solidified lava.The subsequent list shows how many other unstable elements also decay to form the same stable element: Generally, only the decay of uranium 238 is taken into consideration when using the uranium 238/lead 206 method (1).
To date, zircons - known to many as a semiprecious stone and December's birthstone - have often produced confusing and inaccurate results.
Most scientists today believe that life has existed on the earth for billions of years.
This belief in long ages for the earth and the existence of life is derived largely from radiometric dating.
Moreover, in addition to uranium 238, 52 other elements also decay to form lead 206.
The half-life of these elements varies between a few microseconds and 245,500 years.
The existence of two 'parallel' uranium-lead decay routes allows several dating techniques within the overall U-Pb system.
