GODLEVSKITE Meaning and
Definition
-
Godlevskite is a rare mineral that belongs to the halide structural group. It is named after the Russian mining engineer, V. G. Godlevskiy, who first discovered it. This mineral is known for its distinct properties and crystal structure. It typically forms as cubic or octahedral crystals, which are transparent to translucent and have a vitreous luster. The color of godlevskite can range from colorless to pale yellow or greenish-gray.
Chemically, godlevskite consists of a combination of lead, chlorine, and oxygen elements, with its chemical formula being Pb9(Cl,OH)11O4. It has a high density and is relatively soft with a Mohs hardness of 2.5 to 3. This mineral is commonly found in hydrothermal veins associated with lead-zinc ores and other mineral deposits.
Godlevskite has an interesting fluorescence property as it may display a blue-green fluorescence under ultraviolet light. In terms of its optical properties, it has a high refractive index and is optically isotropic, meaning that it exhibits the same physical properties when observed from any direction. This mineral is also pyroelectric, which means it can generate an electric charge when heated or cooled.
Due to its rarity and limited occurrence, godlevskite holds significance in the field of mineralogy and can be a sought-after mineral by collectors or researchers studying halide minerals.
