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

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.

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Late Cenozoic silty and sandy sediments in the semi‐arid Mackenzie basin have been eroded and redeposited almost entirely from nearby Mesozoic greywacke basement. Fine (commonly micron scale) phyllosilicate flakes, including clays, are randomly distributed and randomly oriented, and the sediments are porous.

Mineralogy and Formation of a Platinum Placer Deposit, Southern South Island, New Zealand
New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.Placer platinum group minerals (PGM), with subordinate detrital gold, have been concentrated in Pleistocene coastal sands near the present Foveaux Strait shoreline. This study characterises the PGM in what is New Zealand's only identified PGM deposit.

Observation of centimetre-scale argon diffusion in alkali feldspars: implications for 40Ar/39Ar thermochronology [PDF]
, 2013 New data from a gem-quality feldspar from Itrongay, Madagascar, record naturally occurring 40Ar/39Ar age profiles which can be numerically modelled by invoking a single diffusion mechanism and show that microtexturally simple crystals are capable of ...
