Jun 15, 2020 Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of ironII and ironIII. Its empirical formula is Fe 3 O 4, and it is often expressed as ironII,III oxide. In the past, it has been called ferrousferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.

Biotite Mica The Mineral Biotite Information And Pictures

Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot 1774 - 1862, a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotites abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.
