Core samples recovered from exploration boreholes and granite/greisen outcrops at the Panasqueira world-class tungsten deposit in central Portugal were subjected to chemical analyses petrographic studies. We present a geochemical dataset trace element compositions of quartz micas large part unexposed granitic pluton. Our data suggest that hidden granite body is more complicated than previously ...

Assessing the geochemical signature and role of fluids in a key Variscan detachment zone demonstrates link between crustal deformation, thermo-mechanical events mineralization. We document meteoric fluid infiltration into ductile segment Late-Carboniferous Quiberon (QDZ), when synkinematic muscovite tourmaline crystallized equilibrated with deuterium-depleted surface-derived during high-tempera...

The Yamrang Pegmatite in the Ikhabu Field, Eastern Nepal is Nepal’s primary source of aquamarine. This paper reports detailed mineralogy and whole rock granite pegmatite geochemistry, major trace element data for alkali feldspar muscovite order to classify aquamarine-bearing Pegmatite, elucidate beryl-saturation processes evaluate potential geochemical exploration tools beryl-pegmatites. Five i...

Clay-rich sediments from the Kajjansi, Kitiko, Kitetika, and Ntawo valleys in central Uganda were analyzed for mineralogical and chemical composition, including the rare earth element (REE) contents. The valleys are filled with Quaternary to Recent alluvial and lacustrine sands, silt, and gravels, which formed from the bed rock metasediments of the Buganda-Toro System and from granitoid rocks t...

Located at the eastern segment of Tethyan Himalayan tectonic unit, Cuonadong leucogranites (muscovite granite and pegmatite) have a mineral assemblage quartz, plagioclase, alkali feldspar, as well muscovite garnet. Garnets in both pegmatite belong to almandine–spessartine solid solution, with minor andradite, grossular, pyrope, show specific Mn zoning relatively rim-ward depletion trend. Howeve...
