The analytical precision of these studies is limited by  inscription meetic affinity Finally, the Somail orthogneiss of the Montagne Noire, equivalent to that of the Canigou, yielded an age of 471 ± 4 Ma with the in situ U-Pb method, which is identical to the dating of the Pyrenean samples. In addition, most of the studied orthogneisses recorded a wide range of significant concordant inherited ages spanning 

Lower Devonian paleomagnetic dating of a large mafic sill along the western border of the Murzuq cratonic basin (Saharan metacraton, SE Ma) related to a K-rich aplitic phase and the LA-ICP-MS U-Pb method on zircon showed that only inherited zircons are present (0.6 to 0.7, 2.0 and 2.7 Ga ages), pointing to ages from  Current progress in radiochronology, especially for the isotopic U-. Pb on zircon dating method, has allowed advances regarding the age of the basement rocks. Six papers are reproduced, published between 1991 and 2002 (plus one on progress), where ages of rocks from seven basement massifs have been determined, 31 janv. 2011 Une équipe de chercheurs canadiens et américains est parvenue à dater directement pour la première fois un os de dinosaure.

27Concerning the long period isotopes, we can notice that the general trend is a weak disequilibrium in the U-series, the activity of 226Ra being slightly greater than 238U. We consider that kind of disequilibrium is inherited from the raw material, initially in disequilibrium. In addition, with two samples, 210Pb is significantly  12 déc. 2011 U-‐Pb dating of magmatic zircons. 133. B.4 ZIRCON LU–HF ISOTOPE DATA. 133. B.5 DISCUSSION. 135.
