Loranskite is a mineral that belongs to the perovskite group. It is named after L. G. Loransky, a Russian mineralogist who first described the mineral. It is primarily composed of calcium, titanium, and oxygen, with the chemical formula (Ca,Ti)O3.
Loranskite typically forms as small, well-formed crystals with an isometric crystal system. It has a cubic or octahedral crystal habit and may appear as a transparent or translucent mineral. Its color can vary, ranging from colorless to pale yellow, brown, or black.
This mineral is found in metamorphic rocks, especially those that underwent high-pressure conditions during formation. It is commonly associated with other minerals such as pyroxene, garnet, and quartz. Loranskite has a relatively high hardness on the Mohs scale, ranging between 6 and 7.
One notable feature of loranskite is its strong luminescence under ultraviolet light, often displaying a bright, intense yellow-green glow. This property has led to some interest in its potential applications in fluorescent lighting and other optical devices.
In summary, loranskite is a perovskite mineral composed of calcium, titanium, and oxygen. It forms small crystals with an isometric crystal system and can appear in various colors. It is commonly found in metamorphic rocks and exhibits strong luminescence under ultraviolet light.
