Goethite
Goethite is a common iron-bearing mineral that typically forms in oxidized environments. It is often found in sedimentary rocks and soil, where it contributes to the formation of iron ore deposits. Goethite has a distinctive yellow-brown color and a fibrous or massive texture, making it easily recognizable.
This mineral is named after the German poet and scientist Johann Wolfgang von Goethe, who made significant contributions to the study of minerals. Goethite is an important source of iron and is used in various industrial applications, including the production of pigments and as a raw material in steel manufacturing.
