176Hf/177Hf ratios in magmatic rocks are highly correlated (e.g., Chauvel et al. 2008; Johnson and. Beard 1993; Patchett 1983a; Salters and Hart 1991;

In addition, there are 30 other known radionuclides, the most stable of which is 182 Hf with a half-life of 8.9 × 106 years. 177 Lu-AMBA (AMBA = DO3A-CH 2 CO-G- [4-aminobenzoyl]-QWAVGHLM-NH 2) is being developed for the radiotherapeutic treatment of tumors that express the gastrin-releasing peptide receptor (GRP-R).

Routine low‐blank chemistry and 0.01‐0.04% precision on the ratio 176Hf/177Hf allows study of Hf isotopic variations, generated by β−‐decay of 176Lu, in volcanic rocks derived from the suboceanic mantle. Normalized to 176Hf/177Hf = 0.7325, 176Hf/177Hf ranges from 0.2828 to 0.2835, based on 24 basalt samples. 176Hf/177Hf is positively correlated with 143Nd/144Nd, and negatively

(2004) and the CHUR values of Bouvier et al. (2008). 2017-12-19 · 2 Of the Hf isotopes of interest, 177Hf is free from direct isobaric overlap from any other element and does not typically suffer from polyatomic interference from Blocket - Sveriges största marknadsplats, bilar, bostäder, möbler m.m. The 176Hf/177Hf composition of inherited and magmatic zircon in the 538 Ma S-type Peninsula pluton (South Africa) has been determined at different scales. In the smallest rock samples investigated (<0.5 dm3), as well as within individual thin sections, magmatic zircon crystals exhibit the same wide range in εHf(538) as the pluton (8ε units). No correlation between 176Hf/177Hf and Lu/Hf ratio is observed, suggesting no detectable inhomogeneity in the Hf isotopic ratios due to Lu decay.

The 176Lu-176Hf isotope method and its applications in earth sciences are discussed. Greater fractionation of Lu/Hf than Sm/Nd in planetary magmatic processes makes 176Hf 177Hf a powerful geochemical tracer. In general, proportional variations of 176Hf 177Hf exceed those of 143Nd l44Nd by factors of 1.5-3 in terrestrial and lunar materials.
