To read the time on this radioactive clock, scientists use a device called a mass spectrometer to measure the number of parent and daughter atoms.
The ratio of parents to daughters can tell the researcher how old the specimen is.

For more than three decades potassium-argon (K-Ar) and argon-argon (Ar-Ar) dating of rocks has been crucial in underpinning the billions of years for Earth history claimed by evolutionists. Lassen plagioclase, California (AD 1915) 0.11±0.03 Ma Sunset Crater basalt, Arizona (AD 1064-1065) 0.27±0.09 Ma; 0.25±0.15 Ma Akka Water Fall flow, Hawaii (Pleistocene) 32.3±7.2 Ma Kilauea Iki basalt, Hawaii (AD 1959) 8.5±6.8 Ma Mt.
Critical to these dating methods is the assumption that there was no radiogenic argon ( Hualalai basalt, Hawaii (AD 1800-1801) 1.6±0.16 Ma; 1.41±0.08 Ma Mt. Stromboli, Italy, volcanic bomb (September 23, 1963) 2.4±2 Ma Mt.
Think of the nucleus as a pyramid of building blocks.
If you try to add extra blocks to the sides pyramid, they may stay put for a while, but they'll eventually fall away.
For the original sources of these data, see the references in A. Snelling, "The Cause of Anomalous Potassium-Argon ' Ages' for Recent Andesite Flows at Mt.
Ngauruhoe, New Zealand, and the Implications for Potassium-Argon ' Dating'," R.
Only hard parts, like bones and teeth, can become fossils.
But for some people, the discovery raised a different question.
The result is like a radioactive clock that ticks away as unstable isotopes decay into stable ones.
You can't predict when a specific unstable atom, or parent, will decay into a stable atom, or daughter.
Etna basalt, Sicily (May 1964) 0.7±0.01 Ma Medicine Lake Highlands obsidian, Glass Mountains, California ( in the 1800-1801 Hualalai flow, Hawaii, resided in fluid and gaseous inclusions in olivine, plagioclase, and pyroxene in ultramafic xenoliths in the basalt, and was sufficient to yield "ages" of 2.6 Ma to 2960 Ma.
