Are fossil dating methods accuracy dating variant ru
However, before this time some very popular indirect methods were available.
For example, Lord Kelvin had estimated the ages of both the Earth and the Sun based on cooling rates.
As one answer to his critics, Kelvin produced a completely independent estimate — this time for the age of the Sun.
His result was in close agreement with his estimate of the age of the earth.
The solar estimate was based on the idea that the energy supply for the solar radioactive flux is gravitational contraction.
These two independent and agreeing dating methods for of the age of two primary members of the solar system formed a strong case for the correctness of his answer within the scientific community.
“The fascinating impressiveness of rigorous mathematical analyses, with its atmosphere of precision and elegance, should not blind us to the defects of the premises that condition the whole process.
He believed this even though he did admit that some heat might be generated by the tidal forces or by chemical action.
In his study Rutherford measured the U and He (He is an intermediate decay product of U) contents of uranium-bearing minerals to calculate an age.
One year later Boltwood (1907) developed the chemical U-Pb method.
In these studies the isotopic ratios of all the noble gases (He, Ne, Ar, Kr, and Xe) of neutron-irradiated meteorites were measured.
This led to the discovery of There is, of course, one radiometric dating method that appears to overcome the vital “zero date problem”.
