Zirconium and beryllium are extracted from granite pegmatites (minerals zircon and beryl, respectively). Granite may contain ore minerals. Tin and tungsten ores, for example, are hosted by granite. Granite is an important construction material. It is hard and durable which makes it a very good material for aggregate.
Beryl is the main source of beryllium, which is widely used in nuclear industries, aerospace, and aviation (Khaleal et al. 2022a, b; Suo et al. 2022).Beryllium is a rare element in the upper continental crust (2.1 ppm; Rudnick and Gao 2003).However, it is abundant in granites and related rocks (Giuliani and Groat 2019).Be-rich fluids are commonly associated with …
High-silica granites are significant carriers of highly incompatible elements and are closely associated with mineralization of the rare metal beryllium. Thus, understanding their …
: Beryllium silicate accessory minerals (beryl, gadolinite–hingganite, phenakite and bertrandite) represent useful mineral indicators of magmatic to hydrothermal processes and tectonic environment. It is well documented on examples from contrasting Carboniferous to Permian granite–pegmatite suites of the Western Carpathians (Slovakia).
Beryllium is one of the most widespread rare elements in granitic pegmatites. These rocks have been historically the sole industrial source of this metal (e.g., Norton et al. 1958), …

A special permit gives the right to mine beryllium ores, zinc ores and granite [3]. Geological structure of Sushchano-Perga zone The ore field of the Perga beryllium deposit is located in the central part of the Suschano-Perga tectonic zone and is formed mainly by granites of the Ukrainian shield Perga complex (Fig.3).

These are sometimes called "granite pegmatites" to indicate their mineralogical composition. However, compositions such as "gabbro pegmatite," "syenite pegmatite," and any other plutonic rock name combined with "pegmatite" are possible. ... Examples are small ions such as lithium and beryllium that form spodumene and beryl; or large ions such ...

Le granite peralumineux de Beauvoir (Allier) est relativement riche en beryllium, notamment dans sa partie superieure ou les teneurs depassent 100 ppm. Cependant le beryl est rare et n'explique pas la permanence des teneurs. Le support mineralogique du beryllium a ete recherche par separation densimetrique et dosage a l'I.C.P. Il apparait que cet element est essentiellement …
The newly discovered Oligocene granitoids (33.1–28.7 Ma) at Pagele are magmatic rocks related to beryllium mineralization during the India-Asia late-collisional stage. This …
The three-stage granites and granitic pegmatite, which contain higher beryllium contents or beryls, were likely generated by highly fractionation of the porphyritic granodioritic magma or other homologous magma. Considering the possible genetic and spatial link between Indian slab tear and rifts, we suggest that highly-fractionated granites in ...

Abstract. Beryllium is a critical metal typically concentrated in highly fractionated granitic rocks such as the leucogranites in the Himalaya. Here, we report beryl mineralization that was continuous from the earlier and less-evolved two-mica granite to the highly evolved albite granite and pegmatite in a typical leucogranite pluton at Pusila in the central of Himalaya.
Beryllium minerals in the granite include mostly hydroherderite ( BeO = 15% similar to 16%), and rarely beryllonite, which appear as intergranular accessory minerals in the middle facies of the ...
This chapter addresses the portion of the geochemical cycle of beryllium that entails its transfer through the continental crust by the generation and migration of silicic magmas, …
Beryllium minerals are best known from geologic systems associated with felsic magmatism. They also occur in a variety of settings that lack evident igneous associations. Environments range from the surface to the deep crust and host rocks range ... Beryllonite NaBePO4 non-silicate granite and granitic pegmatites "Glucine" (Gl) CaBe4 ...
dependency of the beryllium industry in the United States on imported beryl, led the Bureau of Mines to study the beryllium potential of domestic pegmatite deposits.
Beryllium contents of granitic melts at saturation in beryl (+ or - chrysoberyl, phenakite, or quartz) have been determined by forward- and reverse-direction experiments at 650-850 degrees C and 200 MPa using natural beryl or the compositionally equivalent mixture of phenakite + alumina + quartz added to metaluminous haplogranite, peraluminous …
The geochemical behavior of beryllium in magmas is poorly known, especially because of difficulties associated with getting representative, small-scale analyses of natural Be-bearing minerals and experimental run products (Charoy 1999).Progress in recent years (e.g., Evensen and London 2002, 2003) has improved our understanding of the behavior of Be in …

Beryllium-bearing granite is divided into two types: acidic rock and alkaline rock. The rock mass is small in scale and appears in the shape of rock strain, rock tongue and rock cap, and the ore body is located on the top or edge of the rock mass. Two mineral combinations are often formed in acid granites: beryllium is the main component, with ...

(2) Beryllium is characterized by high solubility in granite melts, where the BeO content can exceed 2 wt %, which corresponds to its concentration in rich deposits. (3) The high beryllium solubility in the granitoid melt suggests that large beryllium deposits can be formed due to relatively small magmatic bodies.
