Problems with Radiometric Dating

Potassium-Argon radiometric dating is a process by which scientists assign an age to a rock sample by measuring the amounts of Potassium and Argon found within it. It is similar to Carbon dating, which can only be used on materials that were once alive. Potassium-Argon dating is used on rock.

Potassium-40 will decay into Argon-40 at a steady rate. So if scientists know how much Argon is in the rock sample presently (which they do), and if they know how much Argon was in the rock sample when it was formed (which they don’t), and if they know the current rate of decay has always been what it is now (which they don’t), and if they know it has never been contaminated (which they don’t), they could get very accurate readings. Since they don’t know all these facts, they make assumptions—guesses. Of course scientists call their results fact and expect us to swallow their results without debate.

But let me share with you some examples of when Potassium-Argon dating has been proven incorrect:

  • Mt. Etna, in Sicily, erupted in 122 BC. The rock formed in that eruption has been dated at 170,000-330,000 years old.
  • Mt. Etna errupted again in 1972. The rock was dated at 210,000-490,000 years old.
  • Hualalai, in Hawaii, erupted in 1800-1801. The rock has been dated at 1.44-1.76 million years old.
  • Mt. Ngaurahoe, in New Zealand, erupted in 1954. The rock has been dated at 3.3-3.7 million years old.
  • Kilauea Iki, in Hawaii, erupted in 1959. The rock has been dated at 1.7-15.3 million years old.
  • Mount St. Helens erupted in 1986. The rock has been dated at 300,000-400,000 years old.

Did you do the math? Is anyone else having trouble accepting these figures? Perhaps radiometric dating isn’t as accurate as we’ve been told.
