Peralkaline igneous rocks are defined by a molar (Na+ K)/Al ratio> 1 and are subdivided into
miaskitic and agpaitic varieties depending on their mineralogy. In the more common …

Abstract Despite Nb and Ta being considered as 'geochemical twins', most Ta mineral
deposits are associated with muscovite-bearing peraluminous granites and related …

Porphyry deposits arguably represent the most economically important class of nonferrous
metallic mineral resources. These magmatic-hydrothermal deposits are characterized by …

Three major categories of ore deposits—granite-related sensu stricto—were selected for
detailed analysis: disseminated magmatic mineralization in granites themselves (rare metal …

Metal-rich fluids that circulate in magmatic-hydrothermal environments form a wide array of
economically significant ore deposits. Unravelling the origins and evolution of these fluids is …

Abstract The classical S–I–A-type granites from the Lachlan Orogen, SE Australia, formed as
a tectonic end-member of the accretionary orogenic spectrum, the Paleozoic Tasmanides …

The Baerzhe alkaline granite pluton hosts one of the largest rare metal (Zr, rare earth
elements, and Nb) deposits in Asia. It contains a geological resource of about 100 Mt at …

Abstract The Thor Lake rare metal (Zr, Nb, REE, Ta, Be, Ga) deposits in Canada's Northwest
Territories represent one of the largest resources of zirconium, niobium, and the heavy rare …

Abstract The Cenozoic Mianning–Dechang (MD) rare earth element (REE) belt in eastern
Tibet is an important source of light REE in southwest China. The belt is 270 km long and 15 …

Petrological and geochemical observations of pegmatites in the Strange Lake pluton,
Canada, have been combined with numerical simulations to improve our understanding of …
