Changoite is a mineral primarily composed of a combination of calcium, vanadium, and oxygen. It is classified as a rare phosphate mineral and belongs to the apatite group. Changoite typically crystalizes in small, prismatic or acicular needle-like formations, often occurring in radiating aggregates or clusters.
In terms of its physical properties, changoite is known to have a vitreous to resinous luster, meaning it exhibits a shiny or slightly glossy appearance. Its color can vary, ranging from yellowish-green to deep green, and it commonly exhibits an intense fluorescence under ultraviolet light. Changoite has a hardness of 4.5-5 on the Mohs scale, indicating its moderate resistance to scratching.
The mineral derives its name from its discovery locality, the Chango River in Chile, where it was first found. Changoite is mainly found in the oxidized zones of vanadium-bearing mineral deposits. While it is considered a rare mineral, it does occur in a few locations worldwide, including Chile, Argentina, and the United States.
Changoite has limited practical uses due to its scarcity and small crystal size. However, it does serve as an important mineral for collectors and researchers interested in studying vanadium minerals and their properties. Its vibrant color and fluorescence make it an attractive addition to mineral collections, while its chemical composition contributes to our understanding of the geological processes that form such rare minerals.
