Coupling of in-situ Sm–Nd systematics and U–Pb dating of monazite and allanite with applications to crustal evolution studies

In situ Nd isotopic measurement of natural geological materials by LA-MC-ICPMS

“…Our experiments indicated that mass bias of Sm and Nd (β Sm and β Nd ) was not equal, changing with analytical emission ( Figure 2). In addition, the stable 145 Nd/ 144 Nd ratio can be also used to evaluate the feasibility of our method [11,13] . It will be shown below that our normalized 145 Nd/ 144 Nd ratios after isobaric interference correction agree well with the recommended value, within error, of 0.348415 obtained by TIMS [21] .…”

“…Obviously, this approach is an empirical and irrational conclusion. (3) McFarlane and McCulloch [13] proposed that the β Sm value can be directly obtained from the 147 Sm/ 149 Sm ratio on the sample itself and then applied in the isobaric interference correction of 144 Sm on 144 Nd. They also pointed out that these values are ~2% lower than TIMS values owing to the larger mass bias inherent to plasma-source mass spectrometers.…”

Glass Making in the Greco-Roman World: Results of the ARCHGLASS project

“…Sm and Nd are enriched in accessory minerals, such as apatite, titanite, allanite, perovskite, xenotime and monazite (Wedepohl, 1978;Foster and Vance, 2006;McFarlane and McCulloch, 2007). They also occur in trace concentrations in many rock-forming minerals like feldspar, biotite, amphibole and clinopyroxene, in which they replace major ions (Best, 2003;Faure and Mensing, 2005).…”

The zircon archive of continent formation through time

“…Garçon et al 2011;McFarlane & McCulloch 2007;McFarlane & McKeough 2013;Ewing et al 2014;Hammerli et al 2014). As well as U -Pb to provide a crystallization age, the two most common isotopic systems measured in zircon are lutetium -hafnium and oxygen ( 18 O/ 16 O).…”
