Radiometric or Absolute Rock Dating



Explain the principle behind radioactive dating

Glauconite is a good example. For instance, carbon has a half-life of 5, years. So, if you know the radioactive isotope found in a substance and the isotope's half-life, you can calculate the age of the substance. Learn about half-life and how it is used in different dating methods, such as uranium-lead dating and radiocarbon dating, in this video lesson. Because of the expensive equipment necessary and the combination of geologic, chemical, and laboratory skills required, geochronology is usually carried out by teams of experts. Procedure to study: Different methods of radiometric dating can be used to estimate the age of a variety of natural and even man-made materials. The possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created. This scheme is used to date old igneous and metamorphic rocks , and has also been used to date lunar samples. However, local eruptions of volcanoes or other events that give off large amounts of carbon dioxide can reduce local concentrations of carbon and give inaccurate dates.

  1. The uranium content of the sample has to be known, but that can be determined by placing a plastic film over the polished slice of the material, and bombarding it with slow neutrons.

  2. In all cases, it is the obligation of the investigator making the determinations to include enough tests to indicate that the absolute age quoted is valid within the limits stated. The number present is proportional to their decay rate, with long-lived members being more abundant. On the other hand, the concentration of carbon falls off so steeply that the age of relatively young remains can be determined precisely to within a few decades.

  3. In uranium-lead dating , minerals virtually free of initial lead can be isolated and corrections made for the trivial amounts present. The possible confounding effects of contamination of parent and daughter isotopes have to be considered, as do the effects of any loss or gain of such isotopes since the sample was created.

  4. In terms of the numbers of atoms present, it is as if apples changed spontaneously into oranges at a fixed and known rate.
