Article evaluation magnitite everything in the article is related to the topic few grammar an sentence structure areas errors that were distracting seems to be nuetral the points seem to be well represented with all having space and citations but none taking up to much space citation links work (or the ones I checked did) and they back up what has been stated not all statements are sourced, in the opening overview paragraph it states that ancient peoples probably discovered magnetism using magnitite which could be true but there is no citation to something that backs up that statement none of the information seems to be out of date the talk page talks about animal magnetism mainly citation problems and ferrous feric oxide mainly nomenclature it is part of wikiproject geology and is rated c class we have not talked about this in class yet

I could not figure out how to assign myself to the article but I am working with Janet and Mike on Magnetite. I will focus on the distribution of deposits, Mike will focus on properties and Janet will focus on biological occurrences. I plan to expand on where there are magnetite deposits, the time periods the deposits formed and the effect of magnetite on navigation and compass use.

Original in wikipedia

Magnetite is sometimes found in large quantities in beach sand. Such black sands (mineral sands or iron sands) are found in various places, such as Lung Kwu Tan of Hong Kong; California, United States; and the west coast of the North Island of New Zealand.[13] The magnetite, eroded from rocks, is carried to the beach by rivers and concentrated by wave action and currents. Huge deposits have been found in banded iron formations. These sedimentary rocks have been used to infer changes in the oxygen content of the atmosphere of the Earth.[14]

Large deposits of magnetite are also found in the Atacama region of Chile; the Valentines region of Uruguay; Kiruna, Sweden; the Pilbara, Midwest and Northern Goldfields regions in Western Australia; the Eyre Peninsula in South Australia; the Tallawang Region of New South Wales; and in the Adirondack region of New York in the United States. Kediet ej Jill, the highest mountain of Mauritania, is made entirely of the mineral. Deposits are also found in Norway, Germany, Italy, Switzerland, South Africa, India, Indonesia, Mexico, Hong Kong, and in Oregon, New Jersey, Pennsylvania, North Carolina, West Virginia, Virginia, New Mexico, Utah, and Colorado in the United States. In 2005, an exploration company, Cardero Resources, discovered a vast deposit of magnetite-bearing sand dunes in Peru. The dune field covers 250 square kilometers (100 sq mi), with the highest dune at over 2,000 meters (6,560 ft) above the desert floor. The sand contains 10% magnetite.[15]

Magnetite crystals with a cubic habit have been found in just one location: Balmat, St. Lawrence County, New York.[16

Rough draft edits and additions

Magnetite appears in a variety of different geological environments and is a very widespread iron oxide mineral. As magnetite is formed it aligns itself with the earth’s magnetic field at the time of formation and does not change. This is called paleomagnitism and shows a record of the earth’s magnetic field when the magnetite was formed and can show changes in the earth’s magnetic field and polarity through time. If magnetite is in a large enough quantity it can be found in aeromagnetic surveys using a magnetometer which measures magnetic intensities.

Remote sensing has the potential to be a big part in locating magnetite sands as even small amounts of magnetite in sand can drastically alter the sands albedo which is the amount of electromagnetic radiation the sand will reflect. The darker magnetite will lower the sands albedo compared to sands that do not contain magnetite.

In large enough quantities magnetite can affect compass navigation. In Tasmania there are many areas with highly magnetized rocks that can greatly influence compasses. Extra steps and repeated observations are required when using a compass in Tasmania to keep navigation problems to the minimum.

Magnetite crystals with a cubic habit have been found in just one location: Balmat, St. Lawrence County, New York.[16

Magnetite can also be found in fossils due to biomineralization and are referred to as magnetofossils. There are also instances of magnetite with origins in space coming from meteorites.
