From the Answers in Genesis organization website:
"We know that radioisotope dating does not always work because we can test it on rocks of known age. In 1997, a team of eight research scientists known as the RATE group (Radioisotopes and the Age of The Earth) set out to investigate the assumptions commonly made in standard radioisotope dating practices (also referred to as single-sample radioisotope dating). Their findings were significant and directly impact the evolutionary dates of millions of years.3
A rock sample from the newly formed 1986 lava dome from Mount St. Helens was dated using Potassium-Argon dating. The newly formed rock gave ages for the different minerals in it of between 0.5 and 2.8 million years.4 These dates show that significant argon (daughter element) was present when the rock solidified (assumption 1 is false).
Mount Ngauruhoe is located on the North Island of New Zealand and is one of the country’s most active volcanoes. Eleven samples were taken from solidified lava and dated. These rocks are known to have formed from eruptions in 1949, 1954, and 1975. The rock samples were sent to a respected commercial laboratory (Geochron Laboratories in Cambridge, Massachusetts). The “ages” of the rocks ranged from 0.27 to 3.5 million years old.5 Because these rocks are known to be less than 70 years old, it is apparent that assumption #1 is again false. When radioisotope dating fails to give accurate dates on rocks of known age, why should we trust it for rocks of unknown age? In each case the ages of the rocks were greatly inflated."
Yes, it is an organization promoting Creationism, but they have dozens of examples posted as to why radiometric dating should not be trusted.
A rock sample from the newly formed 1986 lava dome from Mount St. Helens was dated using Potassium-Argon dating.
BTW: I was fortunate enough to be an "eyewitness" of the events during the eruption of Mount St, Helens, Sunday, May 18, 1980. Still have some ash samples that fell when the ash cloud covered our city of Yakima, WA.
Quite an experience!
