Extending In-Situ Dating to New Geochronometers: Pb-Pb, Sm-Nd, Re-Os, and LuHf - CKAN

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. Advantages include providing an independent test of concordance, while expanding the potential range of samples that can be successfully measured. Testing for concordance is important because individual isotopic dating systems can be biased by a variety of factors. These biases are frequently distinct for different radiometric systems. Objectives This proposal addresses the important NASA goal to understand the history and evolution of the solar system. The time of key events in solar system history are poorly constrained by current samples, giving impetus to future missions with sample return and in-situ landed dating measurements. An issue for in-situ radiometric measurements is the desire for testing concordance, i.

With an accout for my. Radiometric dating often called radioactive dating is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. Among the best-known techniques are radiocarbon dating , potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.
