Decoding Metamorphic Nanodiamonds Formation Through Their Internal Structures
Journal of Metamorphic Geology, Volume 44, Issue 3, Page 226-245, April 2026.ABSTRACT Metamorphic diamonds offer insights into Earth's evolution, modulating the global carbon cycle through subduction into the mantle and exhumation. However, the formation and internal structure of minute diamonds remain poorly understood. Here, we study the internal structures of diamond‐bearing inclusions from the Eastern Alps using state‐of ...

Anomalously old biotite 40Ar/39Ar ages in the NW Himalaya [PDF]
, 2017 Biotite 40Ar/39Ar ages older than corresponding muscovite 40Ar/39Ar ages, contrary to the diffusion properties of these minerals, are common in the Himalaya and other metamorphic regions.

Th-U-total Pb timing constraints on the emplacement of the granitoid pluton of Stolpen, Germany [PDF]
, 2014 Monazite from the Stolpen monzogranite (SE Germany) was studied to constrain the Th-U-total Pb age of pluton formation. Monazite grains demonstrate subtle to distinct patchy zoning related to slight compositional variations.

Advanced Sensor Research, Volume 5, Issue 3, March 2026.We introduce a new integrated line‐scan sensor system that combines hyperspectral and laser‐induced fluorescence imaging as a non‐invasive alternative characterization technique specifically suited for rare‐earth element (REE) mapping and identification. We investigate in detail the potential and limitations in comparison to state‐of‐the‐art approaches

Asia-Pacific Journal of Chemical Engineering, Volume 21, Issue 2, March/April 2026.ABSTRACT Real‐time online detection of rare earth element component contents is a crucial link in ensuring the stable production of the rare earth extraction and separation industry and improving the quality of rare earth products. The traditional methods for predicting the content of rare earth element components based on just‐in‐time learning fail to

High-pressure structural investigation of several zircon-type orthovanadates
, 2009 Room temperature angle-dispersive x-ray diffraction measurements on zircon-type EuVO4, LuVO4, and ScVO4 were performed up to 27 GPa. In the three compounds we found evidence of a pressure-induced structural phase transformation from zircon to a scheelite-
