... according to the size of the interframework M cations ( Hassan & Grundy 1985 , Nimis et al . 1996 ). Scandium is a very unusual minor element in helvine-group minerals. Borisenko (1963) reported up to 0.1 wt.% Sc 2 O 3 in helvine. Trace amounts varying between 6.84 and 119.8 ppm Sc were found...

... ). The miarolitic NYF pegmatites hosted by the calc-alkaline Baveno pluton contain an important Sc-minerals association. Indeed, six of the 19 known scandium mineral species occur as fine crystals in the cavities of the Baveno granite. Bazzite, Be 3 Sc 2 (Si 6 O 18 ), was the first scandium mineral found...
