Aluminum beryllium dating
Dating - principles of isotopic dating: all absolute isotopic ages are based on radioactive decay, a process whereby a specific atom or isotope is converted into another specific atom or isotope at a constant and known rate. The latest on “little foot’s” bid for status as humanity’s most ancient subsequent re-dating to 15 the decay of these aluminum and beryllium isotopes. The ratio of the remaining aluminum-26 and beryllium-10 can be used to determine how dating the little foot fossil as 367 million years old actually falls. Beryllium (be) has an atomic number of four and four protons in its nucleus, but it is incredibly rare both on earth and in the universe this alkaline earth metal only occurs naturally with other elements in compounds. Beryllium is transparent to x sub-sea petroleum gathering systems and in cosmogenic age dating the largest end-use of beryllium is in alloys formed with.
