- Lutetium–hafnium dating is a geochronological dating method utilizing the radioactive decay system of lutetium–176 to hafnium–176. With a commonly accepted half-life of 37.1 billion years, the long-living Lu–Hf decay pair survives through geological time scales, thus is useful in geological studies. Due to chemical properties of the two elements, namely their valences and ionic radii, Lu is usually found in trace amount in rare-earth element loving minerals, such as garnet and phosphates, while Hf is usually found in trace amount in zirconium-rich minerals, such as zircon, baddeleyite and zirkelite. The trace concentration of the Lu and Hf in earth materials posed some technological difficulties in using Lu–Hf dating extensively in the 1980s. With the use of inductively coupled plasma mass spectrometry (ICP–MS) with multi-collector (also known as MC–ICP–MS) in later years, the dating method is made applicable to date diverse earth materials. The Lu–Hf system is now a common tool in geological studies such as igneous and metamorphic rock petrogenesis, early earth mantle-crust differentiation, and provenance. (en)
- La datation par le lutécium-hafnium est une méthode de datation radiométrique qui repose sur la radioactivité β− de l'isotope 176Lu vers 176Hf. La demi-vie de 176Lu est de 3,86 × 109 ans (la constante de désintégration associée est λ = 1,80 × 10−9 a−1) ; la méthode peut donc être utilisée pour la détermination d'âges de l'ordre du milliard d'années. Son emploi pose cependant des difficultés d'ordre technique. (fr)
