Stability and isotopic dating of monazite and allanite in partially molten rocks: examples from the Central Alps [PDF]
, 2018 We investigated the stability of monazite and allanite as a function of bulk rock composition within several types of Tertiary Alpine anatexites, characterized by different compositions and melting reactions, but similar P-T conditions of melting.

Geostandards and Geoanalytical Research, Volume 49, Issue 4, Page 799-819, December 2025.Key Points New natural high REE/Hf zircon reference material for in situ Hf isotopic measurement. Hf isotope ratio is independent of zircon textural domains. Stable Hf isotope ratio despite Pb and REE variability. Accurate measurements of Hf isotope ratios in zircon rely on adequate correction for isobaric interferences, which increase in complexity as

Advanced Optical Materials, Volume 13, Issue 32, November 14, 2025.A Sb3+‐activated bismuth‐based halide single crystal shifts the onset temperature by ≈200 K. The confluence of the spin‐orbit interaction and the dynamic Jahn–Teller effect is responsible for maximizing the opposite emission changes at different temperatures. A high relative sensitivity (Sr) value of 18.9 % K−1 is obtained at 77 K.

Optimization of the process of obtaining RE 2 O 3 from xenotime using statistical design
CerâmicaThe study of the production of the mixed rare earth oxide (RE2O3) from xenotime via hydrometallurgy was performed to evaluate the significance of the effects of three factors including the melting temperature (A), the ratio of NaOH/xenotime (B), and time

Deeply subducted continental fragments - Part 2: Insight from petrochronology in the central Sesia Zone (western Italian Alps) [PDF]
, 2018 Subducted continental terranes commonly comprise an assembly of subunits that reflect the different tectono-metamorphic histories they experienced in the subduction zone.

Journal of Metamorphic Geology, Volume 43, Issue 8, Page 839-862, October 2025.ABSTRACT Understanding how Paleoproterozoic orogenic processes shaped the assembly of Laurentia remains a critical puzzle in deciphering Earth's ancient tectonic history. To address this challenge, the Montana metasedimentary terrane in the northwest Wyoming Province, which preserves a complex record of multiple metamorphic episodes, provides a unique ...

Fluid or Melt? Distinguishing Syn‐Deformational Interaction Pathways
Journal of Metamorphic Geology, Volume 43, Issue 8, Page 810-838, October 2025.ABSTRACT Understanding whether deformation occurred in the presence of aqueous fluid or silicate melt is crucial for interpreting ductile shear zones, impacting their thermal and geochemical evolution, and having rheological consequences. To identify the syn‐deformational fluid type, we investigate contrasting shear zones active during the Alice ...

Blind spheres of paramagnetic dopants in solid state NMR [PDF]
, 2019 Solid-state NMR on paramagnetically doped crystal structures gives information about the spatial distribution of dopants in the host. Paramagnetic dopants may render NMR active nuclei virtually invisible by relaxation, paramagnetic broadening or ...
