Why is potassium argon dating useful for dating hominids
A very small percentage of the carbon plants take in is radioactive C-14.When a plant or animal dies it stops taking in air and food so it should not be able to get any new C-14.Just this one fact totally upsets data obtained by C-14 dating.
" For years the KBS tuff, named for Kay Behrensmeyer, was dated using Potassium Argon (K-Ar) at 212-230 Million years. It looks like modern humans but was dated at 2.9 million years old. Etna, Sicily (122 BC) gave K-AR age of 250,000 years old. B., 1969 40Ar/36Ar analysis of historic lava flows. Each one has a different half-life and a different range of ages it is supposed to be used for. But even though he used two different dating methods, Swisher kept making the same startling find: the bones were 53,000 years old at most and possibly no more than 27,000 years— a stretch of time contemporaneous with modern humans." --Kaufman, Leslie, "Did a Third Human Species Live Among Us? Radiometric dating would not have been feasible if the geologic column had not been erected first." --O’Rourke, J.One gram of carbon from living plant material causes a Geiger counter to click 16 times per minute as the C-14 decays.A sample that causes 8 clicks per minute would be 5,730 years old (the sample has gone through one half life), and so on. Although this technique looks good at first, carbon-14 dating rests on two simple assumptions.This may be tied in to the declining strength of the magnetic field. Kilauea Iki, Hawaii (AD 1959) gave K-AR age of 8,500,000 years old. The so-called geologic column was developed in the early 1800's over a century before there were any radiometric dating methods. Laboratories will not carbon date dinosaur bones (even frozen ones which could easily be carbon dated) because dinosaurs are supposed to have lived 70 million years ago according to the fictitious geologic column. 124 "A geologist at the Berkeley Geochronology Center, [Carl] Swisher uses the most advanced techniques to date human fossils.Potassium Argon dating: "Potassium Argon dating is based on many of the same assumptions and gives wild dates shown below. "Apart from very 'modern' examples, which are really archaeology, I can think of no cases of radioactive decay being used to date fossils."Ager, Derek V., "Fossil Frustrations," New Scientist, vol. An object's supposed place on the geologic column determines the method used to date it. "One part of Dima [a baby frozen mammoth] was 40,000, another part was 26,000 and the "wood immediately around the carcass" was 9-10,000. Pewe, Quaternary Stratigraphic Nomenclature in Unglaciated Central Alaska, Geological Survey Professional Paper 862 (U. Last spring he was re-evaluating Homo erectus skulls found in Java in the 1930s by testing the sediment found with them.
