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 ...

DISTRIBUTION OF TRACE ELEMENTS IN PEROVSKITE FROM SKARNS AND CALCITE VEINS OF THE CHERNAYA RECHKA AND NAZYAM RIDGES (SOUTH URALS) [PDF]
Минералогия, 2017 Trace element distribution and crystal morphology of perovskite from garnet-vesuvianite skarn of the Akhmatovskaya mine and chlorite-perovskite-calcite veins of the Perovskitovaya mine (South Urals) were studied using LA-ICP-MS.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Deep‐origin carbonatite melts are considered to be the products of partial‐melting of the oceanic crust in the subduction zones. In this study, we conducted electrical conductivity (EC) measurements on two samples, the composition of which resemble the partial‐melting products atop the 410‐km discontinuity and in the lower part of the ...

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.

Magmatic Longevity of Laacher See Volcano (Eifel, Germany) Indicated by U-Th Dating of Intrusive Carbonatites [PDF]
, 2017 Uranium-series dating of carbonatitic ejecta clasts constrains the crystallization and differentiation timescales of the Laacher See volcano, which erupted 6·3 km3 of magma (dense rock equivalent) during one of the largest Late Quaternary eruptions in ...

CO3+1 network formation in ultra-high pressure carbonate liquids [PDF]
, 2019 Carbonate liquids are an important class of molten salts, not just for industrial applications, but also in geological processes. Carbonates are generally expected to be simple liquids, in terms of ionic interactions between the molecular carbonate ...

Resource Geology, Volume 76, Issue 1, January‐December 2026.The western Lugiin Gol REE deposit, related to the Lugiin Gol alkali intrusive complex, consists of carbonatites filling NE‐trending fractures in sedimentary rock. The carbonatites are dominated by carbonate minerals and fluorite and host REE fluorocarbonates, including synchysite‐(Ce), bastnaesite‐(Ce), parisite‐(Ce), and synchysite–bastnaesite ...

Geophysical Research Letters, Volume 52, Issue 24, 28 December 2025.Abstract The Newer Volcanic Province (NVP) in southeastern Australia is a classic example of continental intraplate volcanism located far from a plate boundary, yet the configuration of its magma plumbing system remains unclear. Using three‐dimensional (3D) magnetotelluric (MT) inversion, we imaged a vertically continuous, trans‐lithospheric conductive

Plumes - a new word in Geology of the Urals
Литосфера, 2018 Subject. The ideas of plume tectonics became active and developing only several years later than the theory of plate tectonics. But in the Urals, the question of plume tectonics, contrary to plate tectonics, was not raised, with rare exceptions, until ...
