Question: But how does one know that the magnetic field has fluctuated and reversed polarity? The rubidium-strontium isochron technique suggested that the recent lava flow was 270 Ma older than the basalts beneath the Grand Canyon—an impossibility. This is actually a mini-simulator, in that it processes a different sample each time and generates different dates. Furthermore, the amount of helium in zircons from hot rock is also much more consistent with a young Earth helium derives from the decay of radioactive elements. Logs that show an enormous span of years from one point to another are simply dismissed as contaminated samples. However, this pathway is estimated to be responsible for less than 0.
