Fossils are collected along with rocks that occur from the same strata.

These samples are carefully cataloged and analyzed with a mass spectrometer.

I thank Jay Fischer for reviewing this article and increasing the readability of this work.

By considering radioisotope dating as a problem in trace element detection, and by using the cyclotron as a high-energy mass spectrometer for this purpose, we have shown that one can greatly increase the maximum age that can be determined while simultaneously reducing the size of the sample required.

U-235 decays to Pb-207 with a half-life of 704 million years.

Due to its long half-life, U-235 is the best isotope for radioactive dating, particularly of older fossils and rocks. The half-life of C-14, however, is only 5,730 years.

By comparing this ratio to the half-life logarithmic scale of the parent isotope, they are able to find the age of the rock or fossil in question.

All the data can be interpreted in an approximately 6,000-year-old Earth.However, because of certain factors, we only date igneous and metamorphic rocks, However, there are many problems with these assumptions.
