Dec 10, 2010· Best Answer: The mineral group is Hematite Group Formula: M2O3 also known as the Corundum Group. A group of simple, rhombohedral oxides, where M = Al, Fe, V, Cr, Ti. It needs to be understood how minerals are organized first by class, groups, (some subgroups), and last, species.
Magnetite, iron oxide mineral (FeFe2O4, or Fe3O4) that is the chief member of one of the series of the spinel (q.v.) group. Minerals in this series form black to brownish, metallic, moderately hard octahedrons and masses in igneous and metamorphic rocks and in granite pegmatites, stony meteorites,
Magnetite is a significant ore of iron and as such, is distinguished from other ores of iron by its tendency to attract and get attracted to magnets. Before we jump towards discussing magnetite uses, let's take a closer look at magnetite itself. Read ahead to find out more about magnetite mineral.
Magnetite is one of the end members of the ulvospinel-magnetite solid solution series (Fig. 3.3) and is the most common magnetic mineral on Earth.Magnetite is a cubic mineral with inverse spinel structure. The disordering (Curie) temperature varies more or less linearly with Ti content from -150°C for ulvospinel to 580°C for magnetite (Fig. 3.4 a).
Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).
2.3 Mineral Groups Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2–)) or an anion complex (e.g., SO 4 2–). For example, in the mineral hematite (Fe 2 O 3), the cation is Fe 3 + (iron) and the anion is O 2– (oxygen). We group minerals into classes on the basis of their predominant anion or anion group.
How does the native elements mineral group differ from all of the other mineral groups? On a trip to the natural history museum you find two minerals that are similar in color. You can see from their chemical formulas that one mineral contains the elements zinc, carbon, and oxygen.
Goethite is a common mineral, and is a frequent matrix material for other more aesthetic minerals. It is usually a dark, uninteresting mineral, though specimens from a handful of locations (especially Colorado) are remarkable for their delicate and beautiful crystal growths and velvety botryoidal growths.
Magnetite is an important ore of iron. Well formed crystals are popular among mineral collectors, and the magnetic Lodestone variety is frequently sold in hobby shops to amateur collectors. Magnetite is also of significant interest to the science community due to its strong magnetic properties.
Magnetite is a natural magnet! Part of a mineral group called the oxides, magnetite can usually be identified by its strong magnetism and dark color. Magnetite is often not very abundant, but it can be found in many different types of igneous, metamorphic, and sedimentary rocks. It can even be found in some meteorites.

The minerals that make up the oxide class include those in which oxygen is combined with one or more metals. The minerals are very diverse in their physical properties: they can be quite hard (H=9) and quite soft (H=5) and the colors can range from black to very colorful.

Varieties include kidney ore, martite (pseudomorphs after magnetite), iron rose and specularite (specular hematite). While these forms vary, they all have a rust-red streak. Hematite is harder than pure iron, but much more brittle. Maghemite is a hematite- and magnetite-related oxide mineral.

Minerals are divided into groups based on chemical composition. Most minerals fit into one of eight mineral groups. Silicate Minerals. The roughly 1,000 silicate minerals make up over 90% of Earth's crust. Silicates are by far the largest mineral group. Feldspar and quartz are the two most common silicate minerals.
