Sm-Nd Isotope Data Compilation from Geoscientific Literature Using an Automated Tabular Extraction Method [PDF]

open access: yesScientific Data
The rare earth elements Sm and Nd significantly address fundamental questions about crustal growth, such as its spatiotemporal evolution and the interplay between orogenesis and crustal accretion.

The Sm-Nd isotopic method in the geochronology laboratory of the University of Brasília [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2000
Nd isotopes represent one of the best tools to investigate the processes involved in the evolution of the continental crust and mantle. This is due mainly to the similar geochemical behaviour of Sm and Nd, both light rare earth elements, which inhibits ...

Sm–Nd isotope systematics in deep-sea sediments: clay-size versus coarser fractions [PDF]

open access: yesMarine Geology, 2000
Sm-Nd studies were carried out on Last Glacial and Holocene sediments from the Labrador Sea. Three grain-size fractions were analyzed for each sediment: the clay -size fraction (

Preparation of the Reference Materials for Rb-Sr and Sm-Nd Isotope Analysis

open access: yesYankuang ceshi, 2021
BACKGROUND: One Rb-Sr certified reference materials (GBW04411) and one Sm-Nd certified reference materials (GBW04419) for geological age, which are potash feldspar and basalt respectively, were produced and certified about 30 years ago.

Multi-scale isotopic heterogeneity reveals a complex magmatic evolution: An example from the wallundry suite granitoids of the lachlan fold belt, Australia

open access: yesFrontiers in Earth Science, 2023
Open-system magmatic processes are expected to impart various sorts of isotopic heterogeneity upon the igneous rocks they produce. The range of processes under the “open-system” umbrella (e.g., simple two-component mixing, magma mingling, assimilation ...

Diachronous Redistribution of Hf and Nd Isotopes at the Crystal Scale—Consequences for the Isotopic Evolution of a Poly-Metamorphic Crustal Terrane

open access: yesGeosciences, 2022
In metamorphic rocks, mineral species react over a range of pressure–temperature conditions that do not necessarily overlap. Mineral equilibration can occur at varied points along the metamorphic pressure–temperature (PT) path, and thus at different ...

Characteristics and Provenance Implications of Rare Earth Elements and Nd Isotope in PM2.5 in a Coastal City of Southeastern China

open access: yesAtmosphere, 2022
The source apportionment of fine particulate matters, especially PM2.5, has drawn great attention worldwide. Since rare earth elements (REEs) and Nd isotopes can serve as source tracers, in this study, the characteristics and provenance implications of ...

Constraints on Martian Chronology from Meteorites

open access: yesGeosciences, 2020
Martian meteorites provide the only direct constraints on the timing of Martian accretion, core formation, magmatic differentiation, and ongoing volcanism. While many radiogenic isotope chronometers have been applied to a wide variety of Martian samples,

Systematic Across‐Arc Variations of Molybdenum Isotopes in a Fluid‐Dominated Subduction Zone System

open access: yesGeochemistry, Geophysics, Geosystems, 2023
Mass‐dependent Mo isotope variations are a promising new tracer to study magmatic processes in different geological settings. We report the first Mo isotope data for the Kamchatka arc system in the Northwest Pacific, comprising basaltic lavas of a ...

Petrogenesis and Sr-Nd isotope Geochemistry of Neogene Igneous Rocks in the Goloumak Area, South of Kerman, Iran [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 2023
The study area is near Goloumak village, 30 km south of Kerman. These rock units consist of acidic rhyolite and dacite, as well as intermediate andesite, basalt, and trachy-andesite.
