Listed in in table 5 p. 978 in Liferovich et al. (1998) with Åmli (1977) as the primary source. However Åmli (1977) does not treat bazzite, but thortveitite. A closer view on the table 5 in Liferovich et al. (1998) might indicate that the line discussing bazzite from the Fen Complex, is by a typographical error, placed in the wrong posistion in the table.
