One type of black sand is a heavy, glossy, partly magnetic mixture of usually fine sands containing minerals such as magnetite, found as part of a placer deposit.Another type of black sand, found on beaches near a volcano, consists of tiny fragments of basalt.. While some beaches are predominantly made of black sand, even other color beaches (e.g,Magnetite & Lodestone | Mineral Photos, Uses, Properties,Magnetite sand: Some beach and river sands contain high concentrations of magnetite. Magnetite-rich "black sands" are commonly encountered by people panning for gold. Although magnetite sands and other heavy mineral accumulations are common, they are infrequently developed as mineral deposits because their size or grade is inadequate.Geology - rocks and minerals,Magnetite Magnetite is a natural magnet, hence its name. This is a distinguishing characteristic of the mineral. Magnetite is a common accessory mineral in igneous rocks and is also found as a detrital mineral, particularly on the beaches west of Auckland (black sand).

Discovery date : 1845 Town of Origin : MAGNESIA,Magnetite - Wikipedia,Magnetite is a 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 of,COMPARATIVE STUDIES ON THE BLACK SAND,Fm'ther, it is suggested that the amount of magnetite is an "Index of Maturity" for these residual deposits.

Rocks of Norway
Mountains usually do contain lots of different lithologies, especially when they are older like the Caledonides of Norway are. Another bonus is that mountainous terrain is well exposed and Norway is an especially nice example in this regard.,,,,,
