Geologic dating system erroneous
Discussion of metals and hydrocarbons using the Carlin Au district in western United States concludes that geochronology and its associated isotopic tracers (initial ratios) will be increasingly in demand.
Connecting radiometric ages with their field context provides a critical check on both radiometric accuracy and ore deposit models.
To take this into account, a calibration curve is developed using other dating methods to establish the C14 levels over time.Argon/argon dating works using only the ratio of the concentration of the argon isotopes. For the purposes of this debate, "accurate" means that 95% of the dating errors are within 10% of the measured date, within the time span for which the isotope pair is utilized.Since carbon dating depends upon variable cosmic ray intensity, a calibration curve is assumed to be applied to account for that.This chapter never loses sight of the fact that geologic media are characterized by natural chaos – and the impact of this on geochronology is continually revisited.This paper, like any other, has benefitted from discussion with many people. Heinrich provided the hand samples from the Carlin district.
