Sm-Nd isotopic evolution of chondrites
Earth and Planetary Science Letters, 1980 The ^(143)Nd/^(144)Nd and ^(147)Sm/^(144)Nd ratios have been measured in five chondrites and the Juvinas achondrite. The range in ^(143)Nd/^(144)Nd for the analyzed meteorite samples is 5.3 e-units (0.511673–0.511944) normalized to ^(150)Nd/^(142)Nd= 0.2096. This is correlated with the variation of 4.2% in ^(147)Sm/^(144)Nd (0.1920–0.2000).

Sm-Nd chronology and petrogenesis of mesosiderites
Geochimica et Cosmochimica Acta, 1994 We have obtained Sm-Nd data from four mesosiderite silicate clasts, including three clasts with a variety of textures from the Vaca Muerta type 1A mesosiderite and one gabbroic clast from the Mt. Padbury mesosiderite. The gabbroic Vaca Muerta Pebble 12 and basaltic Pebble 16 yield identical ^(147)Sm- ^(143)Nd ages of 4.48 ± 0.19 AE and 4.48 ± 0.09 AE ...

Evidence for inherited Sm?Nd isotopes in granitoid zircons
Contributions to Mineralogy and Petrology, 1992 This study presents evidence to show that, in addition to preserving U−Pb isotope systematics, refractory zircons also preserve, at least in part, an inherited Sm−Nd isotope component. The zircons analyzed during this study were taken from the Strontian granitoid (NW Scotland). The inner intrusion of this composite pluton is known from a previous study

Sm-Nd isotopic evolution of chondrites and achondrites, II
Earth and Planetary Science Letters, 1984 The ^(147)Sm-^(143)Nd and ^(146)Sm-^(142)Nd isotope systematics have been investigated in five chondrites and the achondrites Moama and Angra dos Reis (ADOR). The new chondrite data and those we have reported before are all consistent with our previously reported reference values for CHUR (“chondritic uniform reservoir”) of (^(143)Nd/^(144)Nd)_(CHUR)^0

Sm-Nd Isotopic Data and Earth's Evolution
Science, 1996Samuel A. Bowring and Todd Housh (1) report Sm/Nd isotopic data giving a wide range of initial ENd values, from +3.5 to -4 at 4.0 billion years ago (Ga) and from +4 to -7 at 3.6 Ga. Their samples were from the Acasta gneisses of northern Canada, which represent the oldest known outcrops of continental crust (2).

Sm(Nd) doped ceria materials for multifunctional application
Ceramics International, 2021Abstract Ceria based solid solution doped by Cu, Mn, Sm(Nd) were synthesized by the co-precipitation method, followed by calcination at the temperature of 500°С. It was shown that all obtained powders of solid solutions crystallized into a cubic structure of the fluorite type, with an average particle size of 4–10 nm.

Sm-Nd isotopic provinces of the Aldan Shield
Doklady Earth Sciences, 2006The formation of the Early Precambrian continental crust is among the most topical problems of modern geology and petrology and has remained a subject of debate for several decades. The Sm‐Nd isotopic mapping, which occupies an important place among modern methods developed for the solution of this issue, makes it possible to estimate the relative ...
