From Wikipedia, the free encyclopedia

Artinite is a hydrated magnesium carbonate mineral with formula: Mg2(CO3)(OH)2·3(H2O). It forms white silky monoclinic prismatic crystals that are often in radial arrays or encrustations. It has a Mohs hardness of 2.5 and a specific gravity of 2.

It occurs in low-temperature hydrothermal veins and in serpentinized ultramafic rocks.

It was first reported in 1902 in Lombardy, Italy. It was named for Italian mineralogist, Ettore Artini (1866-1928).
