Adelite is a mineral species made up of calcium and magnesium arsenate of formula CA MG (ASO 4 ) (OH) . Les cristaux sont de petite taille et n’excèdent pas 5 mm[4].
History of the description and names [ modifier | Modifier and code ]
Inventor and etymology [ modifier | Modifier and code ]
Described by the Swedish mineralogist Sjogren in 1891 [ 5 ] . Of the Greek “adnaldz” = obscure, in allusion to its lack of transparency [ 6 ] .
