GEISKIELITE Meaning and
Definition
-
Geiskielite is a rare mineral that belongs to the anhydrous phosphate group. It is commonly found as a secondary mineral and originated from hydrothermal deposits. Geiskielite is typically formed in oxidized tin-beryllium-bearing granites or pegmatites. It was first discovered in 1962 from the Geiskopf mountain in the Black Forest region of Germany, from which it derived its name.
In terms of chemical composition, geiskielite consists of calcium aluminum phosphate with the chemical formula CaAl[PO4][OH|F]. It crystallizes in the monoclinic crystal system and exhibits pale yellow to colorless prismatic crystals. It possesses a vitreous luster, and its transparency ranges from transparent to translucent. Geiskielite has a hardness of approximately 5.5 on the Mohs scale, indicating its moderate toughness.
Geiskielite is recognized for its interesting optical properties. It displays biaxial positive interference figures and moderate birefringence. This mineral exhibits pleochroism, showing different colors when viewed under polarized light in various crystal orientations.
Despite its limited occurrence, geiskielite has attracted interest from scientific and mineralogical communities due to its intriguing crystal structure and unique composition. Researchers have studied its presence in different geological environments and its association with other minerals. Its aesthetic appeal and relative scarcity have also made it sought after by mineral collectors and enthusiasts worldwide.
