Grey Hill Zircon – A Natural High 176Yb/177Hf Zircon Reference Material for LA‐MC‐ICP‐MS Hf Isotope Measurement

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

Confronting Episodic vs. Continuous Heat Sources in Long‐Lived Hot Orogens: Insights From Petrochronological Studies in the Nova Venecia Complex, Araçuaí Orogen (SE Brazil)

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.
ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

Sedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Forming the Noncarbonaceous Chondrite Parent Bodies in the Presence of the Jupiter Barrier

The Astrophysical Journal
Meteorites can be divided into two groups—noncarbonaceous chondrite like (NC) and carbonaceous chondrite like (CC)—with distinct stable-isotope compositions. Parent bodies of NC and CC meteorites have overlapping formation ages. This suggests they formed

Fe Oxidation State and Oxygen Isotope Composition of Diverse Metasomatized Peridotite Rocks

Terra Nova, Volume 37, Issue 6, Page 403-412, December 2025.
ABSTRACT Metasomatic fluids are thought to be oxidising agents that react with the surrounding mantle rocks, causing changes in the bulk Fe3+/∑Fe, their redox state, and affecting the partitioning of trace elements and the fractionation of O isotopes. Worldwide distributed metasomatized peridotites represent the ideal case study to investigate the role
