Summary of potassium/argon dating, 1981. Topical report
Evans, S.H. Jr.; Brown, F.H.
英文摘要The analytical results for the last fiscal year effort in potassium/argon dating in support of US Department of Energy programs are summarized. Nearly 100 new dates have been generated. Recalibration of the argon extraction tables resulted in refinement of values for tracer ratios and depletion constants for our two extraction lines. Tracer ratios are ({sup 36}Ar/{sup 38}Ar){sub T} = 0.0308 and 0.0000449; ({sup 40}Ar/{sup 38}Ar){sub T} = 0.0501 and 0.0014 for extraction tables 1 and 2, respectively. Tracer depletion constants are -0.0002250 and -0.0005501 for tables 1 and 2, respectively. Initial values for the argon tracer pipettes are 3.2522 x 10{sup -11} moles and 3.9329 x 10{sup -11} moles for tables 1 and 2, respectively.
