Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

University of Minnesota's Mineral Pages: Calcite

As magnetite-bearing igneous and sedimentary rocks form, the magnetite within them is aligned with the Earth's magnetic field. Since this rock magnetism, called paleomagnetism, does not change after the rock forms, it provides a record of what the Earth's magnetic field was like at the time the rock formed.


RELATIONSHIPS BETWEEN MAGNETIC SUSCEPTIBILITY AND ROCK COMPOSITIONS. Oxides and sulfides were lumped together as opaque minerals in point counts of gabbros from Hole 735B (Shipboard Scientific Party, 1989, 1999b); therefore, proportions of ilmenite to magnetite in the rocks were not determined by this means.

Division of Geology and Mineral Resources - Feldspar

The feldspar provides alumina, which improves durability of the glass. The feldspar-rich rock is extracted using open pit methods, then crushed, classified and dried on-site. Heavy minerals are removed from the material by electrostatic and magnetic processes. The processed material is then transported by truck and rail to markets.

Basalt - Wikipedia

Basalt (US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɒ l t /, UK: / ˈ b æ s ɔː l t, ˈ b æ s əl t /) is a mafic extrusive igneous rock formed from the rapid cooling of magnesium-rich and iron-rich lava exposed at or very near the surface of a terrestrial planet or a moon. More than 90% of all volcanic rock on Earth is basalt. Basalt lava has a low viscosity, due to its low silica content ...

Feldspar - Wikipedia

Feldspars crystallize from magma as veins in both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary rocks.

Feldspar Distinctions, Characteristics & Identification

Feldspar is what's called a rock-forming mineral, very common and usually making up a large part of the rock. In sum, any glassy mineral that's slightly softer than quartz is very likely to be a feldspar. The main mineral that might be confused with feldspar is quartz. Besides hardness, the biggest difference is how the two minerals break.
