Type intrusive series of the Far East belt of lithium-fluoric granites and its ore content
Записки Горного института, 2022 The evolution and ore content of granitoid magmatism in the Far East belt of lithium-fluoric granites lying in the Russian sector of the Pacific ore belt have been studied.

Electron Microprobe Chemical Dating of Uraninite as a Reconnaissance Tool for Leucogranite Geochronology [PDF]
, 2007 We suggest that electron microprobe techniques may be employed to date Tertiary samples of uraninite (UO~2~), which can contain very high concentrations of radiogenic Pb after only a few million of years of U and Th decay. Although uraninite is regarded

, 2006 International audienceThe emplacement of the Manaslu leucogranite body (Nepal, Himalaya) has been modelled as the accretion of successive sills. The leucogranite is characterized by isotopic heterogeneities suggesting limited magma convection, and by a ...

The impact of vegetation on fractionation of rare earth elements(REE) during water–rock interaction [PDF]
, 2006 Previous studies on waters of a streamlet in the Vosges mountains (eastern France) have shown that Sr and rare earth elements (REE) principally originate from apatite dissolution during weathering. However, stream water REE patterns normalized to apatite

Tectonics, Volume 45, Issue 2, February 2026.Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.

GeosciencesWe report, for the first time, waimirite-(Y) in Egypt. This is only the third reported occurrence of this mineral in the world. This observation arose during our study of the rare earth element (REE) mineralization associated with the Neoproterozoic rare-

Himalayan Leucogranites: An Experimental Petrology Perspective
ElementsThe High Himalayan leucogranites (HHL) are produced by muscovite breakdown of a metapelitic source, at temperatures below 800 °C, with initial melt water contents of ~5–7 wt.%. The tourmaline-rich HHL variety is colder, possibly a fractionation product of the hotter two-mica HHL.

Acta Geologica Sinica - English Edition, Volume 100, Issue 1, Page 137-155, February 2026.Abstract Elucidating the mineralization mechanisms of individual granitic stages and tracing magmatic evolution processes are critical for establishing mineralization models of large‐scale batholiths. The Mufushan granitoid batholith, renowned for multistage magmatism and large‐scale rare metal mineralization, mainly comprises biotite, two‐mica, and ...

Geologia USP. Série Científica, 2019 Four granitic plutons from the easternmost portion of the São Roque Domain (SRD) were dated by U-Pb zircon SHRIMP; the results indicate that the peak of granitic magmatism was concentrated in a short interval (606–589 Ma), the same as in the central ...
