In the new issue of Geochimica et Cosmochimica Acta (vol. 388, Jan 2025):
Masuda, Y. Schiller, M. Bizzarro, M. et al. Calcium isotope evidence for the formation of early condensates in the Solar System from unmixed reservoirs with distinct nucleosynthe… P 1 .11.010
Grewal, D. S. Bhattacharjee, S. Mardaru, G-D. et al. Tracing the origin of volatiles on Earth using nitrogen isotope ratios in iron meteorites P 34 .11.011
Love those isotopes. In these cases, calcium forms stable silicates, and nitrogen forms stable metal nitrides, so once formed these compounds act as tracers even billions of years afterward and…
Happy 2025, everybody!
