Beach and Shoreline Sands From Around the World

Deze pagina vertalen

Sands on beaches and shorelines can be divided according to their compositions into two major groups. One is the carbonate sands, sands made of particles of CaCO 3 (calcium carbonate). The other is commonly called the "siliciclastic sands", where "silici-" refers to a chemical composition rich in silicate material and "-clastic" refers to the origin of the grains as clasts or fragments of ...

Ironsand - Wikipedia

Deze pagina vertalen

Ironsand, also known as iron-sand or iron sand, is a type of sand with heavy concentrations of iron.It is typically dark grey or blackish in colour. It is composed mainly of magnetite, Fe 3 O 4, and also contains small amounts of titanium, silica, manganese, calcium and vanadium.. Ironsand has a tendency to heat up in direct sunlight, causing temperatures high enough to cause minor burns.

1.1 These test methods cover the chemical analysis of glass sands. They are useful for either high-silica sands (99 % + silica (SiO 2)) or for high-alumina sands containing as much as 12 to 13 % alumina (Al 2 O 3). Generally nonclassical, the test methods are rapid and accurate.
