Carbon dating illustration yahoo dating directory
All three of these isotopes occur naturally in our atmosphere in the following proportions: C12 – 98.89%, C13 – 1.11% and C14 – 0.00000000010% .
The stable isotopes of carbon (12 and 13) were formed when all of our planet’s atoms materialised –a long, long time ago .
Radiocarbon dating, a development in atomic physics, is a case in point.
The importance of this scientific method, however, is far reaching, influencing a multitude of various and independent disciplines such as hydrology, geology, atmospheric science and archaeology to name but a few.
These rogue carbon 14 isotopes, which are produced at a steady rate, are then oxidized and absorbed into the biosphere through the process of photosynthesis and the natural food chain .
Consequently all living things incorporate the atmospheric ratio of C14 to C12 in their geographical area, which is maintained by their metabolic rate .
The problem is that the many individuals across many disciplines that employ radiocarbon dating as a dating device do not understand its nature or purpose. References: William Frank Libby and his team developed the principles of radiocarbon dating during the 1950s.
The pathway from the plant to the molecule may have been indirect or lengthy, involving multiple physical, chemical, and biological processes.
