Investigation of accessory Allanite, Monazite and Rutile of the Barrovian sequence of the Central Alps (Switzerland) [PDF]
, 2018 Accessory Allanite, Monazite and Rutile from amphibolite facies rocks across the Barrovian sequence of the Central Alps (Switzerland) were investigated for textural relationships, composition and U-Th-Pb ages.

Tectonics, Volume 45, Issue 3, March 2026.Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)
Terra Nova, Volume 38, Issue 1, Page 65-76, February 2026.ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Chemical properties of allanite from the Ryoke and Hirosima granite pegmatites in Shikoku, Japan
, 2001 Allanite is one of the most common REE minerals in the Ryoke and Hiroshima granite pegmatites. It generally occurs as prismatic crystal up to 20cm in length to tabular masses in the contact zone of ferro-biotite and feldspar.

Tectonics, Volume 45, Issue 1, January 2026.Abstract The Lower Shear Zone (LSZ) of the Monviso Massif (Western Alps) constitutes a block‐in‐matrix remnant of the subduction plate interface, now tectonically emplaced into the Western Alpine orogenic belt. Here, we combine observations from cartographic to microscopic scales, focusing on garnet‐bearing lithologies in both the mafic blocks and the ...
