MINING ROCKSTAR OF THE WEEK – PYRITE!!
Pyrite is a brass-yellow mineral with a bright metallic lustre. It has a chemical composition of iron sulphide (FeS2) and is the most common sulphide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral. The name "pyrite" is after the Greek "pyr" meaning "fire." This name was given because pyrite can be used to create the sparks needed for starting a fire if it is struck against metal or another hard material. Pieces of pyrite have also been used as a spark-producing material in flintlock firearms - "Geology.com".
