Magnesium Wikipedia

Physical properties. Elemental magnesium is a graywhite lightweight metal, twothirds the density of aluminium. It tarnishes slightly when exposed to air, although, unlike the heavier alkaline earth metals, an oxygenfree environment is unnecessary for storage because magnesium is protected by a thin layer of oxide that is fairly impermeable and difficult to remove.

Clay mineral | rock |

Sepiolite and palygorskite are papyruslike or fibrous hydrated magnesium silicate minerals and are included in the phyllosilicate group because they contain a continuous twodimensional tetrahedral sheet of composition Si 2 O 5. They differ, however, from the other layer silicates because they lack continuous octahedral sheets.
