Beryl: The Gem Mineral of Emerald, Aquamarine, Morganite

Geologic Occurrence of Beryl. Beryl is a mineral that contains a significant amount of beryllium. Beryllium is a very rare metal, and that limits the occurrence of beryl to a few geological situations where beryllium is present in sufficient amounts to form minerals.It mainly occurs in granite, rhyolite, and granite pegmatites; in metamorphic rocks associated with pegmatites; and, in veins and ...

Greisen - Wikipedia

Greisen is a highly altered granitic rock or pegmatite.Greisen is formed by self-generated alteration of a granite and is a class of endoskarn.. Greisens appear as highly altered rocks, partly coarse, crystalline granite, partly vuggy with miarolitic cavities, disseminated halide minerals such as fluorite, and occasionally metallic oxide and sulfide ore minerals, borate minerals and accessory ...

Pegmatite - Wikipedia

Geochemically, pegmatites typically have major element compositions approximating "granite", however, when found in association with granitic plutons it is likely that a pegmatite dike will have a different trace element composition with greater enrichment in large-ion lithophile (incompatible) elements, boron, beryllium, aluminium, potassium ...

Beryllium - Wikipedia

Beryllium is a chemical element with the symbol Be and atomic number 4. It is a relatively rare element in the universe, usually occurring as a product of the spallation of larger atomic nuclei that have collided with cosmic rays. Within the cores of stars beryllium is depleted as it is fused into heavier elements.

BERYL (Beryllium Aluminum Silicate)

Beryl is colorless in pure form; it is the many different impurities that give beryl its varied coloration. Without these splendid color varieties, beryl would be a rather ordinary gemstone with only average fire and brilliance. Emerald is the green variety and Aquamarine is the blue variety of beryl.
