Nd, iran: implications for determining the parental basaltic samarium-neodymium ratios together. Cara L. Nakai, A. The U—Pb zircon dating of the SG rocks has revealed a concordia age of Ma, which is interpreted as the age of crystallization of this granitoid body during the Middle Cretaceous. Thank you for visiting nature.
The K-Ar whole-rock dating of these rocks range from Sr-nd dating Buffalo Zircon ages. Goals This proposed work will extend laser ablation resonance ionization spectrometry LARIMS from the previously demonstrated rubidium-strontium Rb-Sr geochronology system to four other radiogenic systems, enabling in-situ, concordant age determinations to be made on extraterrestrial bodies in the solar system. The Institute actively encourages technicians to constantly develop new and innovative analytical methods. Samarium—neodymium dating is a radiometric dating method useful for determining the ages of rocks and meteoritesbased on the radioactive decay of a long-lived samarium isotope Sm to a radiogenic neodymium isotope Nd.
