COSMIC-RAY EXPOSURE AGE OF THE FARMINGTON METEORITE FROM RADIOACTIVE ISOTOPES
Journal Article
·
· Science See Saiensu
The cosmic-ray exposure age of the Farmington meteorite was found to be greater than 7000 years from the ratio of the carbon-14 and argon-39 present and less than 25,000 years from the ratio of the aluminum-26 and argon-39 present. This exposure age is about an order of magnitude smaller than was estimated previously. (auth)
