Carbon Dating Diamonds

The inclusions in diamonds are direct and unaltered evidence of the processes that took place in the Earth's mantle billions of years ago, at depths that would otherwise be impossible to investigate. This is why their presence, even if it can devalue a diamond as a gem, has an immense scientific value which consists in the possibility of obtaining very important information on the past of our planet. In detail, the study of diamonds has provided important data about the geodynamics and the deep carbon cycle until 3. In other words, to date diamonds we must first date their inclusions and second assume that the calculated age can actually be associated to the diamond formation. This can be easily demonstrated when diamond and inclusion formed at the same time from the same process, but what if the inclusion predates diamond? This case has to be evaluated in terms of time needed by the isotopic system to re-equilibrate, and therefore, to reset the radiogenic clock. If it is rapid, the mineral may isotopically re-equilibrate during diamond formation and provide age data correlated to their entrapment during diamond crystallisation. A new study carried out at the Department of Geosciences, University of Padua, and recently published in Geology , has recently evaluated of reliability of the Sm-Nd dating system applied on clinopyroxene inclusions for dating diamonds if they are pre-existent.

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods.

During the RATE Radioisotopes and the Age of The Earth research project, some of the research effort was focused on investigating radiocarbon carbon dating. D uring the RATE R adioisotopes and the A ge of T he E arth research project at the Institute for Creation Research , co-sponsored by the Creation Research Society , some of the research effort was focused on investigating radiocarbon carbon dating. The RATE radiocarbon research first focused on demonstrating that significant detectable levels of carbon are present in ancient coal beds.
