Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide.

2023年9月4日 · Pyrite, also known as “fool’s gold,” is a common iron sulfide mineral with the chemical formula FeS2. It forms in a variety of geological settings through several processes. Formation: Pyrite forms under reducing conditions, typically in environments with low oxygen levels, high sulfur content, and abundant iron. It can form through both ...

2025年1月24日 · pyrite, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, “fire,” because pyrite emits sparks when struck by metal. Pyrite is called fool’s gold; to the novice its colour is deceptively similar to that of a gold nugget.

Sometimes cruelly known as ‘fool’s gold,’ pyrite is actually much harder than gold and often has flat crystal faces that would not occur in real gold. Although no longer considered a valuable mineral in its own right, pyrite in a rock often signals the presence of other hydrothermal minerals and metal ores that do have significant value.

2024年2月6日 · Pyrite, commonly known as “Fool’s Gold,” is a fascinating mineral that has captivated humanity for centuries. Its shimmering, metallic luster and pale brass-yellow hue have often led to confusion...

Despite its resemblance to gold and its nickname "fool's gold," pyrite has distinct chemical and physical characteristics that differentiate it from the precious metal. Understanding the properties, uses, and occurrence of pyrite is essential for its proper …

As important metal sulfides in the geochemical cycle of sulfur, the characteristics and formation processes of pyrites can provide useful clues regarding their environment.

Detailed description, properties, and locality information guide about the mineral pyrite (fools gold).

Pyrite is a very common mineral (also one of the most common natural sulfides, and the most common disulfide), found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks.

Optical microscopic examination and electron microprobe chemical mapping of pyrites from a variety of mineral deposits, including several high-grade metamorphic ones, reveals that the pyrites frequently contain both physical and chemical textures that may be interpreted in terms of the depositional and the post-depositional history of the deposits.
