A retrograde monazite-forming reaction in bearthide-bearing high-pressure rocks [PDF]
, 2001 Bearthite,Ca2Al[PO4](2)(OH),an aluminium phosphate that may contain up to similar to 10 wt% of light rare-earth elements (LREE) + Th, shows various breakdown textures in high-pressure metamorphic rocks.

Economic evaluation of thorium oxide production from monazite using alkaline fusion method
Nuclear Engineering and Technology, 2021 Monazite is a phosphate mineral that contains thorium (Th) and rare earth elements. The Th concentration in monazite can be as high as 500 ppm, and it has the potential to be used as fuel in the nuclear power system.

Monazite behaviour during isothermal decompression in pelitic granulites: a case study from Dinggye, Tibetan Himalaya [PDF]
, 2017 Monazite is a key accessory mineral for metamorphic geochronology, but interpretation of its complex chemical and age zoning acquired during high-temperature metamorphism and anatexis remains a challenge.

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 601-624, September 2026.Key Points Measurement of 86Sr at count rates < 1500 cps can result in statistical bias. Non‐linear signals in analogue detection mode (e.g., Rb) present a challenge for accurately dating high 87Rb/86Sr mica (> 1000). Accounting for these considerations, high 87Rb/86Sr mica are dated here with accuracies of ∼ 1%.

Geostandards and Geoanalytical Research, Volume 50, Issue 3, Page 625-647, September 2026.Key Points 7 μm spot‐diameter LA‐MC‐ICP‐MS analyses yield accurate zircon U‐Pb ages. 1013 Ω amplifier resistors improve low‐signal Pb measurements. Saturn correction protocols minimise down‐hole fractionation effects. We present a systematic evaluation of high spatial‐resolution zircon U‐Pb dating using a Thermo Scientific Neoma multi‐collector ICP‐MS ...

Journal of the American Ceramic Society, Volume 109, Issue 9, September 2026.Can we make a more inexpensive and greener coating using naturally forming minerals? Xenotime mineral composition was determined to be (Y0.80Gd0.04Dy0.07Er0.05Yb0.04)PO4. Preliminary studies into REPO4 species showed compatable CTE match with SiC, formation of a multilayer reaction product that improves CMAS resistance, and parabolic growth rates ...
