Manganoan calcite (CaCO₃ with Mn replacing some Ca,) pyrite (FeS₂), and sphalerite (ZnS, often contains iron) are often found together in hydrothermal veins and mineral deposits. Each mineral has distinct properties and occurrences but they commonly coexist due to the geological conditions that favor their formation. The combination of manganoan calcite's pink hue, pyrite's metallic luster, and sphalerite's varied colors creates striking and attractive mineral specimens.
Peru and Mexico are notable regions where you can find these three mineral combinations, although they can be seen in other parts of the world.
Some interesting facts are Manganoan calcite often fluoresces bright pink under UV light while Pyrite is commonly known as "fool's gold" due to its metallic luster and brass-yellow color and Sphalerite is the most important zinc ore, critical for the production of galvanizing metal, brass, and other alloys.
