In situ single‐spot Rb/Sr cosmochronology of roedderite in the Ribbeck aubrite (asteroid 2024 BX1)

Meteoritics &Planetary Science, EarlyView.
Abstract The mineralogy and textures of several fragments from the Ribbeck aubrite were analyzed using a combination of scanning electron microscopy, electron microprobe analysis, μRaman spectroscopy, and laser ablation inductively coupled reaction cell mass spectrometry (LA‐ICP‐MS/MS).

Radiogenic and stable isotope measurement using a MC-ICP-MS

Journal of Analytical Science and Technology, 2011
In this study, we presented newly developed analytical methods for radioactive, radiogenic, and stable isotopes using a multi-collector inductively coupled plasma mass spectrometer (MC-ICP-MS), where the elemental purification, and precision and accuracy

Rare Earth Elements Geochemistry and Nd Isotopes in the Mississippi River and Gulf of Mexico Mixing Zone

Frontiers in Marine Science, 2018
Rare earth elements (REE) concentrations were measured in surface waters collected across the salinity gradient in the Mississippi River estuary (i. e., Mississippi River plume, MRP), which includes the near-shore portion of the Louisiana Shelf.

Present day Nd isotopic composition of seawater and sediment leaches from the Pacific sector of the Southern Ocean [PDF]

, 2011
FINAL ID: PP11B-1785 The Southern Ocean plays a key role in the climate evolution of Earth’s history, nevertheless its biggest region, the Pacific sector, has been poorly investigated in comparison to other regions in many paleoceanographic aspects ...

Ryugu Reference Project: Recommendations from the Measurement Definition Team

Meteoritics &Planetary Science, EarlyView.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

Heavy iron isotopes in arc rocks reveal anoxic sediment recycling in subduction zones

Communications Earth & Environment
The formation mechanism of arc mafic rocks with heavy iron isotope signature remains enigmatic. Here we report Fe-Mo-Sr-Nd-Hf isotope data of arc rocks from Northeast China. The studied arc rocks have δ56Fe values (0.08‰ to 0.23‰) comparable to or higher
