Last month, scientists uncovered a mineral called Edscottite. Minerals are solid, naturally occurring substances that are not living, such as quartz or haematite. This new mineral was discovered after an examination of the Wedderburn Meteorite, a metallic-looking rock found in Central Victoria back in 1951.
Edscottite is made of iron and carbon, and was likely formed within the core of another planet. It’s a “true” mineral, meaning one which is naturally occurring and formed by geological processes either on Earth or in outer-space.
But while the Wedderburn Meteorite held the first-known discovery of Edscottite, other new mineral discoveries have been made on Earth, of substances formed as a result of human activities such as mining and mineral processing. These are called anthropogenic minerals.
While true minerals comprise the majority of the approximately 5,200 known minerals, there are about 208 human-made minerals which have been approved as minerals by the International Mineralogical Association.
