Very cool "volcanological" discovery from a museum 😉 ! Olivine samples on basalt and peridot, Eifel and Wiesbaden, Germany. Specimen from the mineralogical collection of the Bally Museum in Schönenwerd, Switzerland (19th century) with old label and box. #Mineralogy @myswitzerland.bsky.social

Hematite is the primary, globally abundant ore of iron (\(Fe_{2}O_{3}\)), typically appearing as matte gray, black, or metallic, though it always leaves a reddish-brown streak. It is used for steel production, pigments, and jewelry. Formed over 2.5 billion years ago by oxygenation in oceans, it thrives in sedimentary environments, has a hardness of 5.5 to 6.5, and usually has a metallic luster.
