Les études combinées de plusieurs isotopes permettent parfois de mieux cerner les problèmes de genèse. C'est le cas des isotopes de l'oxygène, de l'hydrogène, du carbone et du soufre qui, dans les gîtes d'or à jaspéroïdes de l'Utah, montrent que, dans les quartz et carbonates, une grande quantité d'eaux souterraines chaudes est responsable de la formation des gisements (isotope de l'oxygène). Les valeurs des isotopes du carbone impliquent une source sédimentaire avec un peu de carbone magmatique dans les carbonates [...] 2, record 1, French, - isotope%20du%20carbone
