24 i will use the following argon/argon dating formula 25 listed in brent dalrymple’s book: where t is the age in years and j is the special constant if we run a list of eighty argon 40/39 ratios listed 26 in niemeyer’s article through microsoft excel we get eighty dates. To understand argon-argon dating, you need to understand potassium-argon dating the isotope potassium-39 makes up about 93% of natural potassium potassium-40 is radioactive but has such a long half-life that it is primordial - it has been around since the earth was being formed. According to the assumptions foundational to potassium-argon (k-ar) and argon-argon (ar-ar) dating of rocks, there should not be any daughter radiogenic argon (40 ar ) in rocks when they form when measured, all 40 ar in a rock is assumed to have been produced by in situ radioactive decay of 40 k . The radioactive potassium-argon dating method has been demonstrated to fail on 1949, 1954, and 1975 lava flows at mt ngauruhoe, new zealand, in spite of the quality of the laboratory’s k–ar analytical work. New r & d will optimize the process and help in the design of additional instrumentation to analyze different isotopes like 39 argon that has an intermediate age range ideal for young groundwater and ocean circulation studies.
