How Are Natural Magnets Formed On Earth? Are They …

Magnetite is not magnetic when first formed, and most magnetite cannot even be magnetized. For magnetite to exhibit magnetic properties, it needs to have a particular crystal structure and a distinct chemical composition. Magnetite makes up most lodestone, but contains trace amounts of maghemite and other metal ions, in addition to …

Other biogenic sand components are the skeletal remains of entire organisms, such as very small mollusks or single-celled foraminifera. Biogenic sands can also include resistant biological fragments of organisms, such as sponge spicules, or fossil remains of teeth and parts of jawbones. Some biogenic sand components are listed in Table 5.8.

Magnetite (Fe 3 O 4) is a common iron ore mineral in iron ore deposits of metasedimentary and magmatic origin.Magnetite has an inverse spinel structure and is partly altered in near-surface environments to hematite or kenomagnetite (Waychunas, 1991).Hematite is commonly thought to form from oxidation of magnetite in the near …

Magnetite sand, a sample of the element Iron in the Periodic Table

Magnetite sand. Another element (compound actually) from Chris. He panned this sand from a Lake Michigan beach, like panning for gold except you get black magnetic granules instead of rich. It is very magnetic, as you can see from this picture (there's a magnet under the paper, which is making the sand stick up). Source: Chris Carlson

Magnetite

Magnetite is a mineral whose primary component is an iron oxide that contains equal amounts of iron(II) and iron(III). Its empirical formula is Fe 3 O 4, and it is often expressed as iron(II,III) oxide. In the past, it has been called ferrous–ferric oxide and triiron tetraoxide. Magnetite is found in igneous, metamorphic, and sedimentary rocks.
