  2. Radiometric dating - Wikipedia

    en.wikipedia.org/wiki/Radiometric_dating

    Luminescence dating methods are not radiometric dating methods in that they do not rely on abundances of isotopes to calculate age. Instead, they are a consequence of background radiation on certain minerals. Over time, ionizing radiation is absorbed by mineral grains in sediments and archaeological materials such as quartz and potassium ...

    en.wikipedia.org/wiki/Rhenium–osmium_dating

    Rhenium–osmium dating is a form of radiometric dating based on the beta decay of the isotope 187 Re to 187 Os.This normally occurs with a half-life of 41.6 × 10 9 y, [1] but studies using fully ionised 187 Re atoms have found that this can decrease to only 33 y. [2]

    en.wikipedia.org/wiki/Ioannis_Liritzis

    Liritzis is best known for the invention of two novel dating methods. The method for surface luminescence dating (introduced at 1994) where Liritzis extended the principles behind optical dating and thermoluminescence dating to include surfaces last seen by the sun before buried, of carved rock types from ancient monuments and artifacts, made of granite, basalt and sandstone [8] [9] and the ...

  5. Hafnium–tungsten dating - Wikipedia

    en.wikipedia.org/wiki/Hafnium–tungsten_dating

    The radioactive system behind hafnium–tungsten dating is a two-stage decay as follows: 182 72 Hf → 182 73 Ta e − ν e 182 73 Ta → 182 74 W e − ν e. The first decay has a half-life of 8.9 million years, while the second has a half-life of only 114 days, [7] such that the intermediate nuclide tantalum-182 (182 Ta) can effectively be ignored.

  6. Archaeomagnetic dating - Wikipedia

    en.wikipedia.org/wiki/Archaeomagnetic_dating

    Archaeomagnetic dating is the study and interpretation of the signatures of the Earth's magnetic field at past times recorded in archaeological materials. These paleomagnetic signatures are fixed when ferromagnetic materials such as magnetite cool below the Curie point, freezing the magnetic moment of the material in the direction of the local magnetic field at that time.

  9. K–Ar dating - Wikipedia

    en.wikipedia.org/wiki/K–Ar_dating

    Potassium–argon dating, abbreviated K–Ar dating, is a radiometric dating method used in geochronology and archaeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into argon (Ar).
