Separation of Monazite from Placer Deposit by Magnetic Separation
Minerals, 2019 In this study, mineralogical analysis and beneficiation experiments were conducted using a placer deposit of North Korea, on which limited information was available, to confirm the feasibility of development.

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.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract We present elemental geochemistry and multiple isotopic systematics (Re‐Os, Lu‐Hf, Sm‐Nd and Sr) for mantle peridotite xenoliths from Lashaine in northern Tanzania. We use the data to examine how the major Proterozoic tectono‐thermal events that affected the crust of the western Tanzanian craton are imprinted on the lithospheric mantle in the ...

Regional geochemical and geophysical surveys in the Berwyn Dome and adjacent areas, north Wales [PDF]
, 1984 This report describes stream sediment and gravity surveys carried out across the Berwyn Dome and adjacent areas. The gravity survey confirmed the presence of a broad regional Bouguer anomaly low in the central part of the Dome, on which is ...

Ecological Research, Volume 41, Issue 1, January 2026.The Peak Range Volcanics in central Queensland, Australia is naturally enriched with REEs (Rare Earth Elements). Fieldwork was conducted to analyse REEs in plant species occurring in this area. ABSTRACT Rare Earth Elements (REEs) are critical for high‐tech technologies in the green energy transition.

Isotopic geochronology of granitic rocks from the Central Iberian Zone: comparison of methodologies [PDF]
, 2010 Five granitic rocks, concentrically disposed from core to rim, were distinguished in the Castelo Branco pluton. U-Pb-Th electron microprobe monazite ages from granitic rocks are similar and ranging between 297-303 Ma.

Journal of the American Ceramic Society, Volume 109, Issue 1, January 2026.Even if the concentration of photoactive centers is high, concentration quenching may be avoided when the concentration of quenching centers is sufficiently low, and excitation migration through photoactive centers and subsequent deactivation at quenching centers is the main quenching mechanism.

Mineralogy and distribution of critical elements in the Sn–W–Pb–Ag–Zn Huanuni deposit, Bolivia [PDF]
, 2019 The polymetallic Huanuni deposit, a world-class tin deposit, is part of the Bolivian tin belt. As a likely case for a “mesothermal” or transitional deposit between epithermal and porphyry Sn types (or shallow porphyry Sn), it represents a case that ...
