Resource Geology, Volume 76, Issue 1, January/December 2026.Zircon U–Pb dating constrains the Pilok Sn–W granite emplacement at 212–208 Ma, during the Late Triassic post‐collisional extension after the Sibumasu‐Indochina collision. This timing coincides with widespread tin‐bearing granite magmatism throughout Southeast Asia, marking a major regional metallogenic event. ABSTRACT The Pilok Sn–W deposit in western

Monazite, rhabdophane, xenotime & churchite: Vibrational spectroscopy of gadolinium phosphate polymorphs [PDF]
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2018 Rare-earth phosphates with the general formula REEPO4·nH2O belong to four distinct structural types: monazite, rhabdophane, churchite, and xenotime. We report herein the first direct comparison between vibrational spectra of these compounds for the same metal cation i.e. gadolinium.

Tectonics, Volume 44, Issue 12, December 2025.Abstract The Altai Accretionary Wedge in the Mongolian Altai records a polyphase geodynamic evolution involving two extensional–compressional tectonic cycles, constrained by petrostructural analysis and zircon, monazite U–Pb, and Ar–Ar geochronology. The studied section includes a southwestern high‐grade and a northeastern low‐grade domain, previously ...

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.

Acta Crystallographica Section E Structure Reports Online, 2005 Yb[AsO4], ytterbium(III) oxoarsenate(V), adopts the xenotime structure type. Single crystals were obtained in an attempt to synthesize a compound with nominal composition Yb3OCl[AsO3]2 by fusing a mixture of Yb2O3, YbCl3 and As2O3 in a 4:1:3 molar ratio at 1123 K, owing to air-intrusion during the reaction.
