Formula FeS₂] PYRITE

Pyrite is a common mineral in the Earth's crust. Its name comes from the Greek "pyr", meaning fire, in reference to the sparks it produces when struck with steel. This property, due to its hardness and chemical composition, made it a material once used to create fire. From a mineralogical point of view, pyrite is distinguished by its characteristic metallic luster and its brass-yellow color, often confused with gold. Its crystallization usually occurs in the cubic system, forming perfect cube-shaped crystals. However, it can also adopt other crystalline forms such as the octahedron or the pentagonal dodecahedron. The formation of pyrite is related to various geological processes. It is found in sedimentary, metamorphic and igneous rocks. It is often associated with other sulfides such as chalcopyrite or sphalerite, as well as iron oxides. The presence of pyrite in a rock may indicate particular formation conditions, such as an environment rich in sulfur and iron.

Sphalerite is a key mineral in the field of mineralogy, primarily composed of zinc sulfide. It typically occurs as cubic or tetrahedral crystals, often found in association with minerals such as galena and chalcopyrite. Its color ranges from brown to black, although rarer specimens may display red or yellow hues due to the presence of trace elements such as iron. This color variation makes it a sought-after mineral among collectors and mineral enthusiasts. The largest sphalerite deposits are located in regions such as North America, Central Europe, and Australia, making it a globally important mineral for zinc extraction. Geologists and mining engineers carefully study these deposits to optimize zinc extraction and production. Sphalerite is also valued for its unique optical properties. It has a high refractive index, giving it a diamond-like luster, often compared to that of diamonds. This characteristic makes sphalerite attractive for making jewelry and decorative objects.
