Titre: Hematite crystals from Switzerland
Légende: Voir la traduction automatique
Hematite is iron oxide and one of the most abundant and ubiquitous minerals on the earth's surface. It is the source of the red coloration in 'painted deserts' and the red stain seen on rocks everywhere. Although the mineral often appears black, its powder (also known as 'streak') is bright red, a useful feature in identification. Hematite can be powdery, botryoidal, banded or, as in the material from the alpine veins near Gotthard, Switzerland, crystallized. Hematite is the most important ore of iron.
