Pegmatitic rocks are very coarse-grained basement rocks abundant in quartz, feldspar
or/and mica, in places, endowed either with mega crystals of the aforementioned rock …

An important prerequisite to the long-term use of nuclear energy is information on uranium
ore deposits from which uranium can be economically exploited. Hence the basic purpose of …

The~ 180-km-diameter Chicxulub peak-ring crater and~ 240-km multiring basin, produced
by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on …

The strongly incompatible behaviour of uranium in silicate magmas results in its
concentration in the most felsic melts and a prevalence of granites and rhyolites as primary …

Abstract The French Massif Central (FMC) represents the whole West European Variscan
(WEV) belt, in terms of both the geodynamic evolution and the metallic content. Thus, a study …

Silurian organic-rich black shales are widespread and serve as basic source for most U
mineralization throughout the entire Variscan Orogen of Central and Western Europe. In …

Halogens, mainly F and Cl, play key roles in the evolution and rheology of silicic magmas,
magmatic-hydrothermal transition, partitioning of metals into aqueous fluids, and formation …

The ca. 2 by old Bushveld granites were the last major component of the complex to be
emplaced. The granites form a sill-like pluton of batholithic dimensions, with a thickness of 3 …

The Salvezines Massif in northern French Pyrénées has undergone extensive albitization.
The massif consists of gneisses and a leucogranite hosted in Paleozoic sediments (schists …

Albitization is a common process during which hydrothermal fluids convert plagioclase
and/or K-feldspar into nearly pure albite; however, its specific mechanism in granitoids is not …
