In a fascinating discovery, experts at the Bavarian Environment Agency (LfU Bayern) in Germany stumbled upon fragments of one of the rarest minerals on Earth, Humboldtine, during a survey of a historic mineral collection. Humboldtine is a unique iron-carbon-oxygen mineral that contains water and has only been found at 30 locations worldwide. It is primarily observed as a yellow, shapeless mass, and only occasionally forms tiny crystals. This mineral is formed through the reaction of carbon compounds with iron-rich water and oxygen.
The story of Humboldtine dates back to its initial discovery in 1821 by German mineralogist August Breithaupt. The mineral was found in a weathered brown coal deposit near Korozluky in the Czech Republic and was named after the renowned German naturalist Alexander von Humboldt by Peruvian geologist Mariano Eduardo de Rivero y Ustariz. Since then, the mineral has remained a subject of intrigue and study within the scientific community.
