  1. Igneous rocks are formed when magma and lava that have been cooled.
  2. For all other nuclides, the proportion of the original nuclide to its decay products changes in a predictable way as the original nuclide decays over time.
  3. Meteoritics and Planetary Science.

  5. Zircon also forms multiple crystal layers during metamorphic events, which each may record an isotopic age of the event.
  6. Potassium atoms are used to date rocks that have formed from molten rock.

If I wanted to know how old a fossil was which type of dating would I be using? The proportion of carbon left when the remains of the organism are examined provides an indication of the time elapsed since its death. For most radioactive nuclides, what does it mean when the half-life depends solely on nuclear properties and is essentially a constant.

Radiometric dating

Radiometric dating is used mostly on minerals of igenous and metamorphic rocks. The ages of rocks and minerals are found through radiometric age dating. Carbon dating, which is perhaps best known, can only be used for things some thousands of years old at most, dating oops and so is not particularly useful for fossils. Plotting an isochron is used to solve the age equation graphically and calculate the age of the sample and the original composition. They are useful for radiometric dating because they decay at predictable and measurable amounts.
