Mt st helens dating
Yet the experiment remains as one of the cornerstones of the Young Earth movement.Of most people who have heard of this incident before, that's probably about the total depth of what they've heard.Let's begin with a basic understanding of the radiometric dating technique used, K-Ar, or potassium-argon.This dating technique depends on the fact that the radioactive isotope of potassium, K captures one of its electrons and merges with it, turning the proton into a neutron and a neutrino, and converting the potassium into argon.
Potassium-argon dating is done by destructively crushing and heating the sample and spectrally analyzing the resulting gases.
The conventional K-Ar dating method was applied to the 1986 dacite flow from the new lava dome at Mount St. The whole-rock age was 0.35 /- 0.05 million years (Mya). Excess argon within mineral concentrates from the New Dacite Lava Dome at Mount St. Creation Ex Nihilo Technical Journal 10(3): 335-343. module=research&action=index&page=researchp_sa_r01 Henke, Kevin R.
Ages for component minerals varied from 0.34 /- 0.06 Mya to 2.8 /- 0.6 Mya.
The equipment in use at the time at the lab employed by Dr.
Austin, Geocron Laboratories, was of a type sensitive enough to only detect higher concentrations of argon gas.
