Rubidium strontium dating method

More information
An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina State University. To conduct radioisotope dating, scientists evaluate the concentration of isotopes in a material. The number of protons in an atom determines which element it is, while the number of neutrons determines which isotope it is. For example, strontium has 38 protons and 48 neutrons, whereas strontium has 38 protons and 49 neutrons.

One thing that should be made clear from the beginning: The age of a rock is really just a measure of how long it has been since the rock cooled to become a rock, not how long the material has been around. If you take any rock, melt it, and let it cool back to a rock, it will be a new rock with its age clock reset to zero years old. You should keep this in mind when we are talking about determining the age of rocks. A more relevant example: Let us say that a rock is sitting on the surface of the Moon. A billion years after that rock was formed, the rock is covered and remelted by a lava flow. Two billion years after the lava flow that rock is uncovered by an impact and thrown to the surface. The rock is then picked up by an astronaut, brought back to the Earth, and dated.
